mx8m: csf.sh: pad csf blob for u-boot.itb to CSF_SIZE minus IVT header

2023-10-16T06:46:01Z

When built with CONFIG_IMX_HAB, the full FIT image, including stuff tacked on beyond the end of the fdt structure, is expected to be (fdt size rounded up to 0x1000 boundary)+CONFIG_CSF_SIZE. Now, when the FIT image is loaded from a storage device, it doesn't really matter that the flash.bin that gets written to target isn't quite that big - we will just load some garbage bytes that are never read or used for anything. But when flash.bin is uploaded via uuu, it's important that we actually serve at least as many bytes as the target expects, or we will hang in rom_api_download_image(). Extend the logic in the csf.sh script so that the csf blob is padded to CONFIG_CSF_SIZE minus the size of the IVT header.

doc: csf_examples: csf.sh: Remove unneeded export ATF_LOAD_ADDR line

2023-08-19T02:12:53Z

Originally, exporting the ATF_LOAD_ADDR was required, but since binman has been used to generate the flash.bin, it is no longer needed to do such manual export. The ATF address is now passed via binman. Remove the unneeded export ATF_LOAD_ADDR line. Signed-off-by: Fabio Estevam

mx8m: csf.sh: use vars for keys to avoid file edits when signing

2023-07-13T09:29:40Z

The csf_spl.txt and csf_fit.txt templates contain file paths which must be edited for the location of your NXP CST generated key files. Streamline the process of signing an image by assigning unique var names to these which can be expended from env variables in the csf.sh script. The following vars are used: SRK_TABLE - full path to SRK_1_2_3_4_table.bin CSF_KEY - full path to the CSF Key CSF1_1_sha256_4096_65537_v3_usr_crt.pem IMG_KEY - full path to the IMG Key IMG1_1_sha256_4096_65537_v3_usr_crt.pem Additionally provide an example of running the csf.sh script.

imx: hab: Simplify the mechanism

2023-06-24T17:47:02Z

The current mechanism is unnecessarily complex. Simplify the whole mechanism such that the entire fitImage is signed, IVT is placed at the end, followed by CSF, and this entire bundle is also authenticated. This makes the signing scripting far simpler. Signed-off-by: Marek Vasut

global: Move remaining CONFIG_SYS_* to CFG_SYS_*

2022-12-05T21:06:08Z

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini Reviewed-by: Simon Glass

The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE and this makes it imposible to use CONFIG_VAL(). Rename it to resolve this problem. Signed-off-by: Simon Glass
