I'm porting an am335x based board. We have systems either with 256MB
or 512MB RAM. Currently I'm using following code:
ENTRY_FUNCTION(start_am33xx_baltos_sdram, r0, r1, r2)
{
uint32_t sdram_size;
void *fdt;
sdram_size = SZ_256M;
fdt = __dtb_am335x_baltos_minimal_start;
fdt -= get_runtime_offset();
barebox_arm_entry(0x80000000, sdram_size, fdt);
}
This way I always have 256MB "detected" regardless of the used
hardware. Is it possible to let Barebox autodetect RAM size like it is
done in U-Boot?
Another question concerns booting medium. Whether I start from NAND or
MMC I always want to be able to boot from MMC too. Now, if I boot
Barebox from NAND I can see following in devinfo output:
`-- 48060000.mmc
`-- mmc0
How can I make system enumerate MMC partition, so that I can mount
them? "detect mmc0" doesn't help.
When booting completely from MMC, mmco will be enumerated.
