binman: add CST backend selection for i.MX8M signing

2026-08-03T12:31:24Z

Add support for setting the CST backend, both via DT property and CST_BACKEND environment variable. The CST currently supports two backends, 'ssl' and 'pkcs11', with 'ssl' being the default when CST tool is invoked without any -b parameter. Keep 'ssl' backend as the default, but explicitly pass it via the '-b' parameter, unless the user selects 'pkcs11' via either method. Signed-off-by: Marek Vasut Reviewed-by: Simon Glass

board: nxp: Rename board directory from board/freescale to board/nxp

2026-01-28T06:26:50Z

This patch renames the board directory from board/freescale to board/nxp because NXP now provides Board Support Packages (BSPs) and tools for the former Freescale i.MX and other i.MX products. All relevant references have been updated accordingly. This change does not affect functionality. Signed-off-by: Alice Guo Reviewed-by: Fabio Estevam

imx: hab: fix srktool -c usage by removing spaces

2024-12-16T17:35:58Z

The srktool option -c does not allow spaces between certificate filenames. Only commas (',') should separate the filenames. If spaces are incorrectly included, srktool will not display an error or warning message but will only process the first certificate in the list. So adapt documentation accordingly.

imx: hab: add documentation about the required keys/certs

2024-05-24T14:33:15Z

For CST to find the certificates and keys for signing, some keys and certs need to be copied into the u-boot build directory. Signed-off-by: Claudius Heine

Update documentation and use nxp_imx8mcst binman etype for signing of flash.bin instead of previous horrible shell scripting. Reviewed-by: Tim Harvey Signed-off-by: Marek Vasut

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
