phyFLEX boards beginning with 1362.2 have a workaround for this
i.MX6 bug:
ERR006282 ROM code uses nonreset PFDs to generate clocks, which may
lead to random boot failures
On these boards the SD4_DAT3 pin os connected to the CMIC. The CMIC
will reset the board after 10s when the pin isn't toggled.

The rule in barebox is to name the directories after
the modules. As hummingboard is just one of the
carriers for the MicroSOM module, name the directory
accordingly.

Instead of repeating the same lowlevel init for every board
move it to it's own initcall.
Avoids code bloat and shaves off almost 1.5kB of uncompressed
barebox size for a default imx_v7_defconfig build.
For boards wherethe hostname setup was done in the postcore
initcall we move this to a device initcall to get it out of
the way.

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
