SPL: Add support for specifying offset between header and image

2021-07-31T07:49:32+00:00

Some image types (e.g. kwbimage v1) store the offset to SPL binary and offset to U-Boot proper binary in their headers. To avoid reading SPL binary when loading U-Boot proper, add support for specifying offset in struct spl_image_info, which defines the offset from the beginning of the header and the beginning of the executable data. Initial support is added only for SPI, MMC and SATA code. We can extend it later if needed. Signed-off-by: Pali Rohár Reviewed-by: Marek Behún Reviewed-by: Stefan Roese

spl: mmc: Support OP-TEE payloads in Falcon mode

2021-07-27T07:47:40+00:00

In general, Falcon mode means we're booting a linux kernel directly. With FIT images, however, an OP-TEE secure kernel can be booted before linux. Thus, if the next stage is an IH_OS_TEE, this isn't necessarily a problem. Of course, a general solution would involve mmc_load_image_raw_os() only loading the binary, and leaving the decision of suitability to someone else. However, a rework of the boot flow is beyond the scope of this patch. Accept IH_OS_TEE as a valid OS value. Signed-off-by: Alexandru Gagniuc Reviewed-by: Tom Rini Reviewed-by: Patrick Delaunay

spl: mmc: Factor out eMMC boot partition selection code

Factor out eMMC boot partition selection code into default_spl_mmc_emmc_boot_partition() function and implement weak spl_mmc_emmc_boot_partition(), so that architecture or board code can override the eMMC boot partition selection.

We should not be using typedefs and these make it harder to use forward declarations (to reduce header file inclusions). Drop the typedef. Signed-off-by: Simon Glass

spl: mmc: Rename spl_boot_partition() to spl_mmc_boot_partition()

2020-04-22T12:41:57+00:00

This function is only relevant to the MMC driver so calling it spl_boot_partition() might be confusing. Rename it to spl_mmc_boot_partition() to make its purpose more clear (and bring it in line with spl_mmc_boot_mode()). Signed-off-by: Harald Seiler Reviewed-by: Simon Glass

spl: mmc: Rename spl_boot_mode() to spl_mmc_boot_mode()

2020-04-22T12:41:57+00:00

The function's name is misleading as one might think it is used generally to select the boot-mode when in reality it is only used by the MMC driver to find out in what way it should try reading U-Boot Proper from a device (either using a filesystem, a raw sector/partition, or an eMMC boot partition). Rename it to spl_mmc_boot_mode() to make it more obvious what this function is about.

The call to spl_mmc_get_uboot_raw_sector() completely ignores and overwrites the raw_sect value passed from the caller of spl_mmc_load(). Fix this by passing raw_sect to the function and returning the same value in the default case. Signed-off-by: Faiz Abbas Signed-off-by: Lokesh Vutla

spl: mmc: support uboot image offset on main partition

2020-01-16T09:58:52+00:00

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. Signed-off-by: Baruch Siach Reviewed-by: Stefan Roese Signed-off-by: Stefan Roese
