2019-12-06Revert "spl: fix entry_point equal to load_addr"Tom Rini1-2/+2
Due to the (seemingly bogus) assumption of a default CONFIG_SYS_UBOOT_START value we will revert this change for now and evaluate it again for the next release along with changes to CONFIG_SYS_UBOOT_START.

2019-12-05spl: fix entry_point equal to load_addrGiulio Benetti1-2/+2
At the moment entry_point is set to image_get_load(header) that sets it to "load address" instead of "entry point", assuming entry_point is equal to load_addr, but it's not true. Then load_addr is set to "entry_point - header_size", but this is wrong too since load_addr is not an entry point. So use image_get_ep() for entry_point assignment and image_get_load() for load_addr assignment. Signed-off-by: Giulio Benetti <giulio.benetti@benettiengineering.com>

At present the bloblist is set up in spl_common_init() which can be called from spl_early_init(), i.e. before SDRAM is ready. This prevents the bloblist from being located in SDRAM, which is useful on some platforms where SRAM is inaccessible after U-Boot relocates (e.g. x86 CAR region). It doesn't serve much purpose to have the bloblist available early, since very little is known about the platform then, and the handoff info is written when SPL is about to jump to U-Boot.

2019-08-26spl: support booting via RISC-V OpenSBILukas Auer1-0/+6
RISC-V OpenSBI is an open-source implementation of the RISC-V Supervisor Binary Interface (SBI) specification. It is required by Linux and U-Boot running in supervisor mode. This patch adds support for booting via the OpenSBI FW_DYNAMIC firmware. It supports OpenSBI version 0.4 and higher. In this configuration, U-Boot SPL starts in machine mode. After loading OpenSBI and U-Boot proper, it will start OpenSBI. All necessary parameters are generated by U-Boot SPL and are passed to OpenSBI. U-Boot proper is started in supervisor mode by OpenSBI. Support for OpenSBI is enabled with CONFIG_SPL_OPENSBI. An additional configuration entry, CONFIG_SPL_OPENSBI_LOAD_ADDR, is used to specify the load address of the OpenSBI firmware binary. It is not used directly in U-Boot and instead is intended to make the value available to scripts such as FIT configuration generators. The header file include/opensbi.h is based on header files from the OpenSBI project. They are recent, as of commit bae54f764570 ("firmware: Add fw_dynamic firmware").

2019-08-11spl: implement stack usage checkSimon Goldschmidt1-0/+25
This implements a stack usage check in SPL. Many boards start up SPL to run code + data from one common, rather small SRAM. To implement a sophisticated SPL binary size limit on such boards, the stack size (as well as malloc size and global data size) must be subtracted from this SRAM size. However, to do that properly, the stack size first needs to be known. This patch adds a new Kconfig option: - SPL_SYS_REPORT_STACK_F_USAGE: memset(0xaa) the whole area of the stack very early and check stack usage based on this constant later before the stack is switched to DRAM Initializing the stack and checking it is implemented in weak functions, in case a board does not use the stack as saved in gd->start_addr_sp.

2019-04-26watchdog: Implement generic watchdog_reset() versionStefan Roese1-0/+5
This patch tries to implement a generic watchdog_reset() function that can be used by all boards that want to service the watchdog device in U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG. Without this approach, new boards or platforms needed to implement a board specific version of this functionality, mostly copy'ing the same code over and over again into their board or platforms code base. With this new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). This patch also adds a new flag to the GD flags, to flag that the watchdog is ready to use and adds the pointer to the watchdog device to the GD. This enables us to remove the global "watchdog_dev" variable, which was prone to cause problems because of its potentially very early use in watchdog_reset(), even before the BSS is cleared.

It does this by reusing the existing config option SPL_CRC32_SUPPORT to allow leaving out the CRC check on boards where the additional code size or boot time is a problem (adding the CRC check currently adds ~1.4 kByte to flash).

2018-09-25spl: Weed out CONFIG_SYS_TEXT_BASE usageMarek Vasut1-0/+5
The SPL loaders assume that the CONFIG_SYS_TEXT_BASE memory location is available and can be corrupted by loading ie. uImage or fitImage headers there. Sometimes it could be beneficial to load the headers elsewhere, ie. if CONFIG_SYS_TEXT_BASE is not yet writable while we still want to parse the image headers in some local onchip memory to ie. extract firmware from that image. Add the possibility to override the location where the headers get loaded by introducing new function, spl_get_load_buffer() which takes two arguments -- offset from the CONFIG_SYS_TEXT_BASE and size of the data that are to be loaded there -- and returns a valid buffer address or hangs the system. The default behavior is the same as before, add the offset to CONFIG_SYS_TEXT_BASE and return that address. User can override the weak spl_get_load_buffer() function though.

2018-08-01binman: Add a new 'image-pos' propertySimon Glass1-2/+2
At present each entry has an offset within its parent section. This is useful for figuring out how entries relate to one another. However it is sometimes necessary to locate an entry within an image, regardless of which sections it is nested inside. Add a new 'image-pos' property to provide this information. Also add some documentation for the -u option binman provides, which updates the device tree with final entry information. Since the image position is a better symbol to use for the position of U-Boot as obtained by SPL, update the SPL symbols to use this instead of offset, which might be incorrect if hierarchical sections are used.

2018-08-01binman: Rename 'position' to 'offset'Simon Glass1-2/+2
After some thought, I believe there is an unfortunate naming flaw in binman. Entries have a position and size, but now that we support hierarchical sections it is unclear whether a position should be an absolute position within the image, or a relative position within its parent section. At present 'position' actually means the relative position. This indicates a need for an 'image position' for code that wants to find the location of an entry without having to do calculations back through parents to discover this image position. A better name for the current 'position' or 'pos' is 'offset'. It is not always an absolute position, but it is always an offset from its parent offset. It is unfortunate to rename this concept now, 18 months after binman was introduced. However I believe it is the right thing to do. The impact is mostly limited to binman itself and a few changes to in-tree users to binman: tegra sunxi x86 The change makes old binman definitions (e.g. downstream or out-of-tree) incompatible if they use the 'pos = <...>' property. Later work will adjust binman to generate an error when it is used. Signed-off-by: Simon Glass <sjg@chromium.org>

So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry.

2018-04-03spl: fix binman_sym output checkMiquel Raynal1-2/+8
A previous commit introduced the use of binman in the SPL. After the binman_sym call over the 'pos' symbol, the output value is checked against BINMAN_SYM_MISSING (-1UL). According to the documentation (tools/binman/README), when it comes to the 'pos' attribute: pos: This sets the position of an entry within the image. The first byte of the image is normally at position 0. If 'pos' is not provided, binman sets it to the end of the previous region, or the start of the image's entry area (normally 0) if there is no previous region. So instead of checking if the return value is BINMAN_SYM_MISSING, we should also check if the value is not null. The failure happens when using both the SPL file and the U-Boot file independently instead of the concatenated file (SPL + padding + U-Boot). This is because the U-Boot binary file alone does not have the U-Boot header while it is present in the concatenation file. Not having the header forces the SPL to discover where it should load U-Boot. The binman_sym call is supposed to do that but fails. Because of the wrong check, the destination address was set to 0 while it should have been somewhere in RAM. This, obviously, stalls the board.

2017-09-13spl: add newline in debug outputAnatolij Gustschin1-2/+2
With debug enabled, SPL output following these debug prints is on the same line and it is hard to read. Fix it. Signed-off-by: Anatolij Gustschin <agust@denx.de> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2017-08-13spl: dm: use CONFIG_IS_ENABLED to test for the DM optionPhilipp Tomsich1-2/+3
Even though there's now a TPL_DM configuration option, the spl logic still checks for SPL_DM and thus does not pick up the proper config option. This introduces the use of CONFIG_IS_ENABLED(DM) in spl.c to always pick up the desired configuration option instead of having a hard-coded check for the SPL variant.

2017-08-13spl: use TPL_SYS_MALLOC_F_LEN for TPLPhilipp Tomsich1-1/+1
The (upstream) changes to break up SYS_MALLOC_F_LEN for the full U-Boot and the SPL stage, break TPL (if simple malloc is enabled in TPL). This adds support for a TPL-variant of SYS_MALLOC_F_LEN: - adds TPL_SYS_MALLOC_F_LEN - rewrites a test for CONFIG_SPL_SYS_MALLOC_F_LEN to access CONFIG_VAL(SYS_MALLOC_F_LEN) Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Reviewed-by: Simon Glass <sjg@chromium.org>
