fusee: Improve integration with the new logging system ...

fusee: Implement log level configuration from BCT.ini

we need to strip the NO_PREFIX flag so your log_level is corrected for checking against the global

port log.c log.h for fusee-primary ...

refactor printing
remove lib/printk as it is replaced with log
remove lib/driver_utils.h
added log levels as they seem right, might need adjustments

fusee: Add missing const qualifiers (thanks @aveao)

fusee: Add support for firmware version 6.0.0. ...

fusee: Implement splash screen rendering.
fusee: Add minor notes and update lz library.

fusee: Move nxboot hand-off to IRAM. ...

fusee/exosphere: Minor cleanup.

Add and fix copyright notices for better GPL compliance (thanks @naehrwert and @CTCaer).

fusee: Minor bugfixes.

fusee: Fix CAR registers' definition.

fusee: SYSCTR0 was still wrong...

fusee: Disable AHB redirection when necessary. ...

fusee: Add 3.0.0/3.0.1/3.0.2 warmboot fix.

fusee: Implement BootConfig and Boot Reason handling.

fusee-primary: Fix always false conditional in xmemmove ...

This was corrected in 4b8455b for
fusee-secondary, but I neglected to also fix it in fusee-primary (my
bad!)

fusee: Fix register definition.

fusee: Complete re-write of the hardware initialization code: ...

- Updated code to match hekate's;
- Improved nxboot (now boots firmwares 2.x successfully);
- Temporarily disabled built-in boot system module support;
- Fixed multiple bugs.

Define wait() in fusee-primary/secondary

Fix multiple issues reported by Coverity Scan

fusee: Disable the SDCLK when switching to low voltage.

fusee: Fix SDMMC high speed support and other bugs.

Fusee: Deployed new SDMMC driver in fusee-secondary. All stages boot now. ...

Fusee: Fixed wrong argument in se.c function.
Fusee: Improved timers.

fusee: Correct wrong comment (thanks @desowin)

fusee: SDMMC driver re-design: ...

- Based on hekate's, linux's and u-boot's source code;
- Full support for SD and MMC;
- Fixes multiple issues;
- Deployed first in fusee-primary.

fusee: Code cleanup and style fixes.

Rework sdmmc clocking configuration ...

Use 204 MHz as host clock in SDR104 mode instead of 136 MHz.
Due to this, also change the frequency init divider so the
initialization frequency is below 400 kHz.
This makes the clocks for SDMMC1 in all modes to match the TRM table.

Make it clear in the code that HS200/HS400 modes in fact use PLLP_OUT0
and not PLLC4_OUT2_LJ like the comment suggest. In fact selecting the
PLLC4_OUT2_LJ as clock source results in freeze after switching to
HS200/HS400 mode. This is most likely related to the PLLC4 not being
enabled, but it should be checked later.

Set the HS200/HS400 divider to 3, as this is what the code really did
set prior to this change - so this commit does not change that.

Configure Legacy 12 MHz clock to run at 12 MHz using the SW default
configuration (as per TRM) for the SDMMC legacy timer.

Introduce initial version of sdmmc_host_clock_delay() in order to use it
in places where the wait is host clock dependent. The way it is
implemented now does not change the sleep that was used instead.

fusee: Run periodic autocal only on the uSD controller (#137)

Merge pull request #132 from tslater2006/master ...

Add sdmmc_dump_regs function

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.

Switched to mmc_debug, and use inttypes

Add sdmmc_dump_regs function

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.

Pass screen status and mmc struct from stage1 to 2
