mode" The CONFIG_SPL_FORCE_MMC_BOOT config flag is not needed as its behavior is the correct one in all cases; using spl_boot_device() instead of the boot_device parameter will lead to inconsistency issues, for example, when a board_boot_order() is defined. In fact, this is the reason the parameter was introduced in the first place, in commit 2b1cdafa9fdd ("common: Pass the boot device into spl_boot_mode()").

For Allwinner SoCs the CONFIG_SYS_SPI_U_BOOT_OFFS value is not really a board choice: The boot ROM only loads the SPL from offset 0 of the SPI NOR flash, and loads at most 32KB. This is a similar situation as on MMC, so consequently we create our "joint" image (SPL + U-Boot proper) with that 32KB offset during the build. So define the value of this symbol to be 32KB by default for every Allwinner SoC. This removes the definition of this symbol from the _defconfig files, and avoids every board to define this over and over again.

2020-01-16spl: mmc: support uboot image offset on main partitionBaruch Siach
On Armada 38x platforms the ROM code loads SPL from offset 0 of eMMC hardware boot partitions. When there are no boot partitions (i.e. SD card) the ROM skips the first sector that usually contains the (logical) partition table. Since the generated .kwb image contains the main U-Boot image in a fixed location (0x140 sectors by default), we end up with the main U-Boot image in offset of 1 sector. The current workaround is to manually set CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR to 0x141 to compensate for that. This patch uses the run-time detected boot partition to determine the right offset of the main U-Boot partition. The generated .kwb image is now compatible with both eMMC boot partition, and SD card main data partition.

2020-01-07spl: fit: Allow the board to tell if more images must be loaded from FITJean-Jacques Hiblot
spl_fit_get_image_name() is used to get the names of the images that the SPL must load from the FIT. It relies on the content of a property present in the FIT. The list of images is thus statically defined in the FIT. With this scheme, it quickly becomes hard to manage combinations of more than a handful of images. To address this problem, give the board driver code the opportunity to add to the list of images. The images from the FIT property are loaded first, and then the board_get_fit_loadable() is called to get more image names.

At the start, OpenSBI relocates itself to its link address. If the link address ranges of U-Boot SPL and OpenSBI overlap, the relocation can lead to code corruption if a hart is still running U-Boot SPL during relocation. To avoid this problem, the main hart is specified as the preferred boot hart to perform the relocation. This fixes the code corruption problems based on the assumption that since the main hart schedules the secondary harts to enter OpenSBI, it will be the last to enter OpenSBI. However it was reported that this assumption is not always correct. To make sure the assumption always holds true, wait for all secondary harts to acknowledge the call-function request before entering OpenSBI on the main hart.

The request is considered to be acknowledged once each secondary hart has cleared the corresponding IPI. As part of the call-function request, the secondary harts invalidate the instruction cache after clearing the IPI. This adds a delay between acknowledgment (clear IPI) and fulfillment (call function) of the request. We want to use the acknowledgment to be able to judge when the request has been completed.

2019-12-10spl: opensbi: specify main hart as preferred boot hartLukas Auer
OpenSBI uses a relocation lottery to determine the hart to relocate OpenSBI to its link address. In the U-Boot SPL boot flow, the main hart schedules the secondary harts to enter OpenSBI before doing so itself. One of the secondary harts will therefore always be the winner of the relocation lottery. This is problematic if the link address ranges of OpenSBI and U-Boot SPL overlap. OpenSBI will be relocated and therefore overwrite U-Boot SPL while some harts may still run it, leading to code corruption. Avoid this problem by specifying the main hart as the preferred boot hart to perform the OpenSBI relocation. The main hart will be the last hart to enter OpenSBI, relocation can therefore occur safely. The boot hart field was added to version 2 of the OpenSBI FW_DYNAMIC info structure. The header file include/opensbi.h is synchronized with include/sbi/fw_dynamic.h from the OpenSBI project to update the info structure. The header file is recent as of commit 7a13beb21326 ("firmware: Add preferred boot HART field in struct fw_dynamic_info").
