Ok, I guess I was pessimistic. There is a weird bug in mxc_spi.c: CPOL is
negated!
I just saw that in the mx51evk.h header file CONFIG_FSL_PMIC_MODE was set to
low-active clock (CPOL=1), which is not supposed to work. But it did work, and
on the scope clock-polarity was active-high.
In spi_cfg(), I saw this line:
if (!(mode & SPI_CPOL))
sclkpol = 1;
AFAIK, this should be:
if (mode & SPI_CPOL)
sclkpol = 1;
At least for the MX51. Can you confirm that this is different on the MX31?
Now I get a correct flash id.
