Also we can enable m24c02 eeprom chip in dts-file e.g.
&i2c0 {
status = "okay";
eeprom: m24c02@50 {
compatible = "spd";
reg = <0x50>;
};
};
Alas! qemu mips malta spd m24c02 eeprom chip emulation is not perfect:
the block read operation does not work properly.
Here is an example.
If we read eeprom content byte-by-byte then there is no problem:
barebox:/ for i in 0x08 0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f ;
> do i2c_read -b 0 -a 0x50 -r $i -c 1 ; done
0x01
0x75
0x54
0x00
0x82
0x08
0x00
0x01
Compare this output with content of qemu.git/hw/mips/mips_malta.c:
static eeprom24c0x_t spd_eeprom = {
.contents = {
...
/* 00000008: */ 0x01,0x75,0x54,0x00,0x82,0x08,0x00,0x01,
But if we read several bytes at once the we have data corruption:
barebox:/ i2c_read -b 0 -a 0x50 -r 0x8 -c 8
0x01 0xff 0xff 0xff 0xff 0xff 0xff 0xff

Commit 0d6392de4a introduced a stripped
down device tree used for both white and black Beaglebone variants
that included the 256 MiB memory node from am335x-bone-common.dtsi.
This leads to the following error in the MLO:
mmu: Critical Error: Can't request SDRAM region for ttb at 9fff4000
This patch removes the (for the Beaglebone black) invalid memory size
from the common device tree and instead registers the memory bank
manually in the board file.

We used to relocate the executable to the current address. This does
not work when the executable runs from a readonly location like for
example NOR Flash. Test if we run from inside the available memory and
if we do, relocate to the current address as before. Otherwise copy
the executable to the start of memory and relocate to that address.
While at it add some comments to the code.
