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

Rename CONFIG_SYS_TEXT_BASE to CONFIG_TEXT_BASE

2022-10-31T15:01:31Z

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

mx8m: csf.sh: Fix the calculation of fit_block_size

2022-09-21T14:19:45Z

When running the script to sign SPL/U-Boot on a kontron-sl-mx8mm board, the fit_block_size was calculated as 0x1000 instead of 0x1020. Add an extra parenthesis pair to fix it. Signed-off-by: Fabio Estevam Reviewed-by: Marek Vasut
