2022-02-21arm64: zynqmp: Fix debug uart initializationMichal Simek1-10/+22
The commit 0dba45864b2a ("arm: Init the debug UART") calls debug_uart_init() from crt0.S but it won't work because SOC is not configured yet. That's why create board_debug_uart_init() which calls psu_init() via new psu_uboot_init() earlier before the first access to UART in SPL. In full U-Boot call psu_uboot_init() only when CONFIG_ZYNQMP_PSU_INIT_ENABLED is enabled.

The commit 985503439762 ("fdt: Don't call board_fdt_blob_setup() without OF_BOARD") forced to enable OF_BOARD for platforms which provide DT externally. Zynq/ZynqMP boards are using this feature for a long time that's why there is a need to enable it by default. Also code expects to return error in case of error that's why also fill it.

2022-02-01xilinx: common: change bootm_size to not go beyond ram_topRicardo Salveti1-1/+1

2021-09-30ARM: zynq: Enable capsule update for qspi and mmcMichal Simek1-0/+35
Generate dfu_alt_info setup at runtime for capsule update. Enabling this feature will help with upgrading boards without remembering what is where. The similar change was done for ZynqMP by commit b86f43de0be0 ("xilinx: zynqmp: Add support for runtime dfu_alt_info setup"). Code needs to be enabled by CONFIG_SET_DFU_ALT_INFO. And also enable capsule on disk for RAW firmware images with efidebug command. Two indexes are supported for SPL flow. Images can be generated like: ./tools/mkeficapsule --raw spl/boot.bin --index 1 capsule1.bin ./tools/mkeficapsule --raw u-boot.img --index 2 capsule2.bin Then place them to SD card and load them: load mmc 0 10000000 capsule1.bin && efidebug capsule update -v 10000000 load mmc 0 10000000 capsule2.bin && efidebug capsule update -v 10000000 FSBL flow will also work where only index 1 capsule is used.

2021-08-26xilinx: common: Enabling generic function for DT reselectionMichal Simek1-6/+78
U-Boot support board detection at run time and based on it change DT. This feature is implemented for SOM Kria platforms which contain two eeproms which contain information about SOM module and CC (Carrier card). Full U-Boot starts with minimal DT file defined by CONFIG_DEFAULT_DEVICE_TREE which is available in multi DTB fit image. It is using default setup of board_name variable initializaed to DEVICE_TREE which corresponds to CONFIG_DEFAULT_DEVICE_TREE option. When DTB_RESELECT is enabled board_detection() is called. Keep it your mind that this code is called before relocation. board_detection() is calling xilinx_read_eeprom() which fills board_info (xilinx_board_description) structure which are parsed in board_name_decode(). Based on DT configuration and amount of nvmemX aliases name of the board is composed by concatenating CONFIG_SYS_BOARD "-" <board_name> "-rev" <board_revision> "-" <cc_name> "-rev" <cc_revision>. If CC is not present or more are available it keeps going. When board name is composed and returned from board_name_decode() it is assigned to board_name variable which is used by board_fit_config_name_match() which is called via fdtdec_setup() when it goes over config options in multi dtb FIT image. From practical point of view multi DTB image is key point here which has to contain configs for detected combinations. Unfortunately as of now they have to be full DTBs and DTBOs are not supported. That's why configuration like: config_X { description = "zynqmp-board-cc"; fdt = "board", "cc"; }; needs to be squashed together with: fdtoverlay -o zynqmp-board-cc -i arch/arm/dts/zynqmp-board.dtb \ arch/arm/dts/zynqmp-cc.dtbo and only one dtb is in fit: config_X { description = "zynqmp-board-cc"; fdt = "board-cc"; }; For creating multi DTBs fit image use mkimage -E, e.g.: mkimage -E -f all.its all.dtb When DTB_RESELECT is enabled xilinx_read_eeprom() is called before relocation and it uses calloc for getting a buffer. Because this is dynamic memory it is not relocated that's why xilinx_read_eeprom() is called again as the part of board_init(). This second read with calloc buffer placed in proper position board_late_init_xilinx() can setup u-boot variables as before. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2021-08-26xilinx: Use variable for passing board_nameMichal Simek1-2/+4

2021-08-06xilinx: zynqmp: Free allocated field for target variableMichal Simek1-0/+1
When env_set() is called there is no need to allocate memory for variable which is already saved that's why free it. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2021-08-02global: Convert simple_strtoul() with hex to hextoul()Simon Glass4-33/+33
It is a pain to have to specify the value 16 in each call. Add a new hextoul() function and update the code to use it. Add a proper comment to simple_strtoul() while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-07-26arm64: zynqmp: Do not define do_reset() if sysreset is enabledMichal Simek1-0/+2
The SPL can also be compiled with sysreset drivers just fine, so update the condition to cater for that option. The same change was done by commit efa1a62ad2dd ("ARM: imx8m: Do not define do_reset() if sysreset is enabled"). Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2021-07-26xilinx: Return ENVL_NOWHERE instead of ENVL_UNKNOWNMike Looijmans2-6/+6
The system refuses to boot without any environment, so return ENVL_NOWHERE when there's nowhere to store the environment instead of ENVL_UNKNOWN. This fixes that the board won't boot from eMMC when CONFIG_ENV_IS_IN_FAT is not defined, for example. Similar for other combinations.

2021-07-26mmc: zynq_sdhci: Split set_tapdelay function to in and outAshok Reddy Soma1-35/+38
Split arasan_zynqmp_set_tapdelay() to handle input and output tapdelays separately. This is required to handle zero values for ITAP and OTAP values. If we dont split, we will have to remove the if() in the function, which makes ITAP values to be overwritten when OTAP values are called to set and vice-versa. Restrict tap_delay value calculated to max allowed 8 bits for ITAP and 6 bits for OTAP for ZynqMP.
