Add sdmmc_dump_regs function
 2018-06-10 16:21:18 +01:00
Tomasz Moń 804a40830e Fix race conditions and misconfiguration in sdmmc 
Properly configure pull up and pull down offsets for autocal.
Run autocal prior to every transfer.

Prevent race conditions in sdmmc_wait_for_event() - make sure the fault
handler has highest priority, then the target irq, state conditions and
finally the error mask.

Do not clear all bits (|=) when acknowledging fault conditions,
only acknowledge the fault conditions itself.

Enable interrupts before preparing command registers - if sdmmc is fast
enough it can actually finish transfer before we enabled the interrupts.
Enabling interrupts clears the COMMAND COMPLETE status bit.

Temporarily print all the sdmmc messages in stage2 - for yet unknown
reason respecting the log level results in some failures.

This results in working microsd card in stage2 on my switch with Samsung
EVO+ 256GB microsd card.

Tomasz Moń 7b9dcd2f1a Make sdmmc autocalibration follow TRM procedure 
Sleep for 1 us, not 1 ms.
Timeout after 10 ms, set driver strength code values according to TRM.

Fix typo (mS) - time is in milliseconds, not milliSiemens.

Tomasz Moń 0534e36cf8 Set SDMMC controller to SDR104 as a workaround 
According to Tegra X1 Series Processors Silicon Errata there is possible
misalignment of received data which results in a CRC error. The issue is
present only in SDR50 mode.
