CONFIG_SAMA5D3xEK_528MHZ=y
Basic operation at 528MHz has been verified but is not the default in
these configurations because most testing was done at 396MHz.
- The apps/system/ramtest runs without errors, but runs very slowly.
It looks like it takes about 90 seconds to test 1MiB of RAM. That
means that a full 256MiB RAM test should take about 6 hours. That
is too long. This implies that there is something wrong with the
SDRAM configuration.
- Similarly, while attempting to calibrate the delay loop, I find that
the 100s calibration delay runs for a very long time. This is not
correct, of course, with a higher CPU clock, the calibration delay
should be shorter if anything!
- NAND time has not been tested.
these configurations because most testing was done at 396MHz. NAND
has not been verified at these rates.
2) Most of these configurations execute from NOR FLASH. I have been unable
to execute these configurations from NOR FLASH by closing the BMS jumper
