Hi Sören, Andre,
The Kconfig spelling fix looks correct, but I think enabling that path
in gpio_init() needs another look. I ran into this while looking at the
A733, which also selects NCAT2.
Ah yes, I noticed this already back then, but forgot to reply to Soeren:
my apologies. Thanks to Vinicius for the heads up!
So yes, we need new code to setup the withstand registers.
Patches welcome!
Cheers,
Andre
The code copies PIO+0x348 to PIO+0x340, using the H6 power-mode offsets.
That matches the R528/T113 layout, but on the A523 family the power-mode
registers are at 0x388/0x380 instead. So the fix would make the SPL
write a different register at 0x340 on boards that are already supported
upstream.
I built U-Boot next (ed869863) with and without the patch for avaota-a1,
radxa-cubie-a5e and mangopi_mq_r. The copy isn't in any of the SPLs
before the patch and is in all three after it.
I haven't tested this on A523 hardware, so I can't report a boot
failure. But the register layout suggests the copy should be limited to
SoCs where those offsets are valid, rather than enabled for all NCAT2.
Thanks,
Vinicius
