This will fix everything that uses a timer (or sleep).
Without this any function like eMMC/SD read/write/verify, TSEC/SE, etc can break when the time reaches the max value of the u32 microsecond timer (71minutes).
This fixes every possible breakage, including backup and restore (read/write/verify errors) that takes a lot of time.
The new max before a timer reset is now 48 days (the old one was 71 minutes)
* [INI] Fix memory leaks + other fixes
* Add ini_free
* check and return if NULL pointer in free()
* Add button check with timeout
* Fix a bug in menu rendering that tries to parse a string without existing
* Change initial cnt value to max (fixes menus with first entry not a selectable entry)
* Some & ? clarifications
* [INI] Add get selected boot cfg
- This allows to free ini as we launch the firmware and have the lowest mem leak
* [INI] Rename ini section clone/free functions
- Sanitize framebuffer. Original idea from @StevenMattera
- Change clear framebuffer to memset (for grey colors), for performance (we don't use alpha blending, so it does not matter to set it to 0xFF).
- Enable screen backlight after gfx init
- Reduce wait time for emmc/sd read/write retries to 100ms.
Now that the cid/csd/ssr/etc bytes/bitfields are correct:
* MMC/SD: Add cid/csd parsing and use new cid/csd variables
* SD: Add ssr (sd status) reading/parsing
* MMC/SD: Change many hardcoded values to named ones
* MMC/SD: Fix scr and csd byte/bitfield ordering
* MMC: Add ext csd parsing and using these variables isntead of arrays
* MMC: Fix BKOPS support but disabled
* SD: Add partial sd v1 support
* SD: Fix we support low voltage OCR bit
* SD: Add scr parsing and using these variables instead of hardcoded ones
Some vendors, *I'm looking at you Samsung*, report support for 1.8 voltage, even though the card does not support it.
So, disable low voltage support for now until the behavior is changed to act more like what Linux does. (re-initializing the SD card and disables the low voltage switch).
Fix the switch to high speed mode for high voltages also.
Additionally, correct the IF COND reply. 0xAA is the important part.
