spl: Set spl_image->fdt_addr pointer for full fitImage configuration

2019-05-18T16:32:00Z

Set the spl_image->fdt_addr pointer both for simple fitImage configuration as well as full fitImage configuration, to let spl_perform_fixups() access the DT and perform modifications to it if necessary. Signed-off-by: Marek Vasut Cc: Tom Rini

spl: implement CRC check on U-Boot uImage

2019-02-19T13:55:43Z

SPL currently does not check uImage CRCs when loading U-Boot. This patch adds checking the uImage CRC when SPL loads U-Boot. 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). The SPL_CRC32_SUPPORT config option now gets enabled by default if SPL support for legacy images is enabled to check the CRC on all boards that don't actively take countermeasures.

SPL: Add HAB image authentication to FIT

2019-01-01T13:12:18Z

Introduce two board level callback functions to FIT image loading process, and a SPL_FIT_FOUND flag to differentiate FIT image or RAW image. Implement functions in imx common SPL codes to call HAB funtion to authenticate the FIT image. Generally, we have to sign multiple regions in FIT image: 1. Sign FIT FDT data (configuration) 2. Sign FIT external data (Sub-images) Because the CSF supports to sign multiple memory blocks, so that we can use one signature to cover all regions in FIT image and only authenticate once. The authentication should be done after the entire FIT image is loaded into memory including all sub-images. We use "-p" option to generate FIT image to reserve a space for FIT IVT and FIT CSF, also this help to fix the offset of the external data (u-boot-nodtb.bin, ATF, u-boot DTB). The signed FIT image layout is as below: -------------------------------------------------- | | | | | | | | | FIT | FIT | FIT | | U-BOOT | ATF | U-BOOT | | FDT | IVT | CSF | | nodtb.bin | | DTB | | | | | | | | | -------------------------------------------------- Signed-off-by: Ye Li Reviewed-by: Peng Fan Reviewed-by: Tom Rini Signed-off-by: Peng Fan

spl/tpl: change banner into upper case

2018-12-07T13:13:51Z

commit d6330064634a ("spl: Add a define for SPL_TPL_PROMPT") changes the SPL/TPL banner from upper case into lower case. As SPL and TPL are three-letter acronyms and they are written in upper case, change it back to upper case. Signed-off-by: Heiko Schocher Reviewed-by: Simon Glass

spl: Add support for passing handoff info to U-Boot proper

2018-11-26T13:25:37Z

There is some basic informaton that SPL normally wants to pass through to U-Boot, such as the SDRAM size and bank information. Mkae use of the new bloblist structure for this. Add a new 'handoff' blob which is set up in SPL and passed to U-Boot proper. Also adda test for sandbox_spl that checks that this works correctly and a new 'sb' command to show the information passed from SPL. Reviewed-by: Tom Rini Signed-off-by: Simon Glass

spl: Add a define for SPL_TPL_PROMPT

2018-11-26T13:25:34Z

We should use a macro rather than hard-coding the SPL prompt to 'spl' since the code can be used by TPL too. Add a macro that works for both and use it in various places. This allows TPL to use the same code without printing confusing messages. Note that the string is lower case ('spl', 'tpl') which is a change from previously.

spl: add support to booting with OP-TEE

2018-10-04T19:15:46Z

OP-TEE is an open source trusted OS, in armv7, its loading and running are like this: loading: - SPL load both OP-TEE and U-Boot running: - SPL run into OP-TEE in secure mode; - OP-TEE run into U-Boot in non-secure mode; To make code simple, it would be fine to use IH_OS_TEE for the os tyle in TPL(just like IH_OS_LINUX is using both in SPL and U-Boot). Here is the diagram for SPL loading OP-TEE, IH_OS_TEE:(make u-boot.itb for SPL) Non-Secure Secure BootROM | v SPL | v --------- OP-TEE | v U-Boot | V Linux For other two king of OP-TEE loading/booting, see commit message: 45b55712d4 image: Add IH_OS_TEE for TEE chain-load boot More detail: https://github.com/OP-TEE/optee_os and search for 'boot arguments' for detail entry parameter in: core/arch/arm/kernel/generic_entry_a32.S Signed-off-by: Kever Yang Cc: Bryan O'Donoghue Reviewed-by: Philipp Tomsich

spl: Weed out CONFIG_SYS_TEXT_BASE usage

2018-09-26T01:48:43Z

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.
