2019-12-05MLK-23088 imx8mn: Fix u-boot hang when ENV_IS_NOWHERE is enabledcaf/imx_4.14.98_8qxpc0_erYe Li1-1/+1
By default we enable two env storage devices: SD/emmc or Flexspi. And u-boot will select it according to boot device. Some customer does not save env, so he removes these storage devices and enable ENV_IS_NOWHERE. But current env_get_location does not process the ENV_IS_NOWHERE, returns ENVL_UNKNOWN and causes u-boot hang.

2019-12-05MLK-23081 imx8mn: Change SPL malloc and BSS addressYe Li1-5/+5
Android's build has large size of SPL which overlays with malloc pool, and causes DDR FW image destroyed by the malloc. Adjust some SPL addresses to align with iMX8MQ and allow SPL + DDRFW using the 312 KB OCRAM from 0x912000 to 0x960000. Since the max DDR FW size is 96KB, we set max SPL size to be 216KB.

2019-09-27MLK-22622 imx8m: Add Workaround for ROM SError issueYe Li2-0/+46
ROM SError happens on two cases: 1. ERR050342, on iMX8MQ HDCP enabled parts ROM writes to GPV1 register, but when ROM patch lock is fused, this write will cause SError. 2. ERR050350, on iMX8MQ/MM/MN, when the field return fuse is burned, HAB is field return mode, but the last 4K of ROM is still protected and cause SError. Since ROM mask SError until ATF unmask it, so then ATF always meets the exception. This patch works around the issue in SPL by enabling the SError exception and take it to eret immediately to clear the SError.

When enable u-boot splash screen and set kernel dtb with -hdmi.dtb on imx8qm, the kernel reboot (partition reboot) will hang in u-boot if HDMI cable is plugged in.
