Enable support for booting U-Boot image from ext filesystem when either SD/MMC or SATA support is compiled into the SPL. This will allow easy transition from loading U-Boot image from ad-hoc offset on the card to loading U-Boot image from the filesystem. VFAT support is intently not enabled. The boot order is tweaked so that raw is tested first and if the raw has no signature, FS boot is attempted. To install just the SPL on i.MX6 board, perform the following operation $ dd if=SPL of=/dev/sdX seek=2 bs=512 To install the U-Boot image, copy u-boot.img to the first partition of the SD/MMC/SATA drive. The partition must be formated to extfs.

* - IMX6SDL OCRAM (IRAM) is from 0x00907000 to 0x0091FFFF
|
|
* - IMX6DQ has 2x IRAM of IMX6SDL but we intend to support IMX6SDL as well
|
|
* - BOOT ROM stack is at 0x0091FFB8
|
|
* - if icache/dcache is enabled (eFuse/strapping controlled) then the
|
|
* IMX BOOT ROM will setup MMU table at 0x00918000, therefore we need to
|
|
* fit between 0x00907000 and 0x00918000.
|
|
* - Additionally the BOOT ROM loads what they consider the firmware image
|
|
* which consists of a 4K header in front of us that contains the IVT, DCD
|
|
* and some padding thus 'our' max size is really 0x00908000 - 0x00918000
