[PATCH v3] imx8mm-cl-iot-gate: Split the defconfigs
by Fabio Estevam 07 Oct '21

07 Oct '21

Currently imx8mm-cl-iot-gate_defconfig fails to produce a working boot binary due to the lack of fip.bin: " BINMAN all Image 'main-section' is missing external blobs and is non-functional: blob-ext Some images are invalid" To make the build process more consistent with the other i.MX8M targets, split the defconfig in two: - imx8mm-cl-iot-gate_defconfig: standard defconfig that only requires ATF / DDR firmware. - imx8mm-cl-iot-gate-optee_defconfig: "more advanced" defconfig that requires ATF / Optee / mbedtls / DDR firmware.

[PATCH] imx: mx7: spl: fix CONFIG_SPL_MAX_SIZE definition

The CONFIG_SPL_MAX_SIZE definition did not account for all areas that are used by the boot ROM according to the manual, causing boot failures due to truncated SPL images when actually hitting this limit.

[PATCH][RFC] tree: imx: remove old fit generator script
by Andrey Zhizhikin 07 Oct '21

07 Oct '21

Since derivatives are moving to binman from usage of the FIT generator script, and considering the warning introduced in f4a43d2925 ("Makefile: Warn against using CONFIG_SPL_FIT_GENERATOR"), usage of FIT generator is discouraged. Current FIT generator also generates broken output, since commit 3f04db891a ("image: Check for unit addresses in FITs") prohibits using '@' for unit addresses but the generator script still emits the old sematics. Remove the generator script and corresponding call in Makefile, all derivatives should be migrated to binman in order to provide binary images.

[PATCH v2 0/1] arm: imx8m: imx8mm-cl-iot-gate: Add support for detect memory size
by Ying-Chun Liu 07 Oct '21

07 Oct '21

From: "Ying-Chun Liu (PaulLiu)" <paulliu(a)debian.org> When purchasing imx8mm-cl-iot-gate it is able to customize the memory size. It could be 1GB, 2GB and 4GB. We implement board_phys_sdram_size() to detect the memory size for usage. This patch was trying to fix the regression on mainline U-boot for imx8mm-cl-iot-gate. However this is not related to the regression. But we should have this implemented anyway. v2: use hang() instead of while(1) Ying-Chun Liu (PaulLiu) (1): arm: imx8m: imx8mm-cl-iot-gate: Add support for detect memory size .../imx8mm-cl-iot-gate/imx8mm-cl-iot-gate.c | 25 +++++++++++++++++++ 1 file changed, 25 insertions(+) -- 2.32.0

[PATCH v1 0/2] imx8m: fix secure boot
by Heiko Schocher 07 Oct '21

07 Oct '21

This series fixes secure boot on imx8m based boards. Tim also detected this issue and the patches fixed on his hardware also the problem, see discussion here: https://lists.denx.de/pipermail/u-boot/2021-July/454351.html Problem is that the IVT header gets loaded to a memallocated buffer, but it needs to sit on memaddress coded in IVT header itself. This patchseries adds a weak function spl_load_simple_fit() in common spl code, which does not change current code behaviour. Second patch than implements this weak function for imx based boards (if no IVT header is found on address which is passed to it, it does nothing). I am not sure if this is the best solution, but it fixes a real bug, and may could be made clearer, if possible.
