libre: uboot4extlinux-am335x: fix filesystem corruption
Before that u-boot.img was to be located at 384k on the microSD, as CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR defaults to 0x300. CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR states: Address on the MMC to load U-Boot from, when the MMC is being used in raw mode. Units: MMC sectors (1 sector = 512 bytes). However since once built, u-boot.img size was 692k, it went over the 1MB empty space that is usually created when parititoning block devices, effectively corrupting the first partition. Signed-off-by: Denis 'GNUtoo' Carikli <GNUtoo@cyberdimension.org>
