These changes fix SPI boot on the SanCloud BBE Lite and other AM335x boards.
They also put us in a good place to enable SPL_OF_CONTROL for eMMC/SD card boot on AM335x boards. Note that if SPL_OF_CONTROL is enabled, some SPL features need to be dropped due to the limited amount of sram available. In my testing I dropped NAND, NET & USB support.
This series has been build tested for all targets using buildman and no errors were observed. It has been boot tested on the SanCloud BBE Lite with the following configurations:
1) SD card boot using am335x_evm_defconfig with no config changes. 2) SD card boot using am335x_evm_defconfig with the following config changes: CONFIG_SPL_OF_CONTROL=y CONFIG_SPL_OF_TRANSLATE=y CONFIG_SPL_MUSB_NEW=n CONFIG_SPL_NAND_DRIVERS=n CONFIG_SPL_NAND_ECC=n CONFIG_SPL_NAND_BASE=n CONFIG_SPL_NET=n CONFIG_SPL_USB_GADGET=n 3) SPI boot using am335x_evm_spiboot_defconfig with the following config changes: CONFIG_DEFAULT_DEVICE_TREE="am335x-sancloud-bbe-lite" CONFIG_OF_LIST="am335x-sancloud-bbe-lite"As discussed in my previous message [1], I can't see how to construct a test case to accompany the first patch which fixes an SPL crash during the pre-relocation lists_bind_drivers() call due to exhaustion of the available memory. We can discuss this further though if anyone has any ideas on how to write an appropriate test case.
