2022-04-04arm: init: save previous bootloader dataDzmitry Sankouski1-0/+13
When u-boot is used as a chain-loaded bootloader (replacing OS kernel), previous bootloader leaves data in RAM, that can be reused. For example, on recent arm linux system, when chainloading u-boot, there are initramfs and fdt in RAM prepared for OS booting. Initramfs may be modified to store u-boot's payload, thus providing the ability to use chainloaded u-boot to boot OS without any storage support. Two config options added: - SAVE_PREV_BL_INITRAMFS_START_ADDR saves initramfs start address to 'prevbl_initrd_start_addr' environment variable - SAVE_PREV_BL_FDT_ADDR saves fdt address to 'prevbl_fdt_addr' environment variable Signed-off-by: Dzmitry Sankouski <dsankouski@gmail.com> Cc: Tom Rini <trini@konsulko.com>
2022-03-10event: Convert arch_cpu_init_dm() to use eventsSimon Glass1-11/+0
Instead of a special function, send an event after driver model is inited and adjust the boards which use this function. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-03-10event: Convert misc_init_f() to use eventsSimon Glass1-1/+0
This hook can be implmented using events, for the three boards that actually use it. Add the event type and event handlers. Drop CONFIG_MISC_INIT_F since we can just use CONFIG_EVENT to control this. Since sandbox always enables CONFIG_EVENT, we can drop the defconfig lines there too. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-01-18common: board_r: move init_addr_map() to init.hOvidiu Panait1-0/+10
asm/mmu.h include is currently guarded by CONFIG_ADDR_MAP ifdef because the header is only present on arm and powerpc. In order to remove the dependency on this header and the associated ifdef, move init_addr_map() declaration to init.h, since it is only called during the common init sequence.

2021-02-03bdinfo: Rename function names to be clearerBin Meng1-1/+2
At present we have bdinfo_print_num() to print unsigned long numbers. We also have print_phys_addr() which accept numbers that might be 64-bit on a 32-bit platform. Rename these 2 functions to be clearer: bdinfo_print_num() => bdinfo_print_num_l() print_phys_addr() => bdinfo_print_num_ll() While we are here, make bdinfo_print_num_ll() public so that it can be used outside cmd/bdinfo.c in the future.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-4/+4
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-08-06board_f: Introduce arch_setup_bdinfo initcallOvidiu Panait1-0/+12
Certain architectures (ppc, mips, sh, m68k) use setup board_part1 and setup_board_part2 calls during pre-relocation init to populate gd->bd boardinfo fields. This makes the generic init sequence cluttered with arch-specific ifdefs. In order to clean these arch-specific sequences from generic init, introduce arch_setup_bdinfo weak initcall so that everyone can define their own bdinfo setup routines.

This reverts commit c0434407b595f785fc7401237896c48c791b45fd. It turns out commit c0434407b595 broke some boards which have DM CPU driver with CONFIG_DISPLAY_CPUINFO option on. These boards just fail to boot when print_cpuinfo() is called during boot. Fixes are already sent to ML and in u-boot-dm/next, however since we are getting close to the v2018.11 release, it's safer we revert the original commit.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. 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. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
