Tested on MacOS Sequoia (Apple Silicon) with the
latest Xcode command line tools, gcc 14
(Homebrew GCC 14.2.0_1) and sdl2 (Homebrew 2.30.9)
Make sure 'gcc' (and 'gcc-ar') is in your PATH
ahead of the Xcode-provided "gcc"(clang). E.g.
by setting up symlinks in /usr/local/bin that
point to gcc-14 and gcc-ar-14.
Notes:
- The appropriate bmp from uisimulator/bitmaps
has to be manually copied to your build folder
and renamed to UI256.bmp, if you want the sim
background to be displayed

This allows to reuse a register definition across similar SoCs that have the same layout of registers (same offsets), but are using a different base address for the peripheral. The include guard was also fixed to reflect the new file name of the header.
Some registers were renamed in order to match the datasheet and for consistency with the other register numbering.

This is part of the preparation to add support for iPod Nano 3G and Nano 4G. There are some optimisations left, like merging similar blocks of registers that share the same layout, but the base address have changed between SoC generations.

Support hw4 units with AXP2101 PMU
Bootloader successfully compiles and loads onto device.
The LCD appears to be identical to hw3 units.
Scroll wheel and buttons work
Audio output works, including volume.
HP/LO detect works
Rockbox build is generic
GPIO gating logic seems to be working as intended now.
- Added new GPIO definitions - some significant overlaps with pins
from previous hardware revisions...
- Added some GPIO definitions for older players we didn't know about
- Add register definitions for AXP2101 from datasheet
(these are very different from AXP192!)
- Add AXP2101 regulator definitions, need to support multiple step
sizes per regulator.
- Verify AXP2101 voltage set multi-range logic
- Verify AXP2101 voltage get multi-range logic
- Make AXP2101 its own driver
- AXP2101 driver should be "minimally viable", though I think
there is some extra functionality that could be implemented.
- Disabling the coulomb counter stuff - we could maybe make
the E-Gauge work for the same purpose, but it only appears to
be used on the debug screen at the moment so it doesn't seem
like it's worth the effort.
- Found new button GPIOs
- Found error in my GPIO setting logic, blue light works now!
- Set LDO/DCDC output voltages to OF's settings, as far as
I can tell.
- Determined we probably want TCS1421_CFG1:0 to be 0x00,
for UFP behavior
- Tested this rb build with both old and new bootloaders on hw1.5,
hw2, hw4 in as many configurations as I can think of, works across
the board.
- Bootloader can install itself on hw4, so nand chip isn't novel
- Uninstallation file can be made by patcher script, works on hw4
- Installation file can be made by patcher script, works on hw4
- Added HW4 to rbutil, manual

Due to its similarity with S5L8702, clickwheel support and sleep can be used as-is on S5L8720. DRAM and IRAM are also configured.
Change-Id: I52f8a3417e6a25c7360b1cae2fb5eed621e2e0db
This is a driver for the UART controller on the S5L87xx series of SoCs, which is named after the SoC family.
Since S5L8720 is confirmed to have the same interface and the newer models probably also have it, the driver is renamed to reflect this.

No functional change.
We always have it turned in for ipod6g, but this makes some of the
flow/logic easier to follow.

Basically this requires un-hardcoding SECTOR_SIZE everywhere, in
favor of using a variable containing what was reported in IDENTIFY INFO.
Note that the rest of the storage subsystem still needs to be fixed up!

This lets us *natively* handle varying physical sector sizes
without playing games and lying about the logical sector size.
(The original drives use 4K _physical_ sectors with 512B logical
sectors, but you have to access everything in 4K blocks...)
Achieve this by splitting the MAX_PHYS_SECTOR_SIZE code out
of the main ATA driver and re-using it.
Change-Id: I0bc615ab4562f1e3e83171a8633c74fb60c7da1f
....It's specified in 16-bit words, not bytes. So multiply it by 2.
(This hasn't been a problem in practice as everything uses 512B logical
sectors so far..)

* FLUSH_EXT is used if featureflag is set and we are using LBA48
(unconditionally used for CE-ATA on ipod6g)
* FLUSH is used if featureflag is set (ATA6+) or if device claims to be ATA5+
* Rename ata_disk_can_power_off() to ata_disk_can_sleep() as that is
what it actually tests for. Only use it to gate issuing the
STANDBY IMMEDIATE command.
* Restore behavior of ata_disk_is_active() to return 1 if drive is
"spinning" or powered up.
* Allow poweroff if drive claims PM support OR we are able to issue
FLUSH/FLUSH_EXT commands.
* Added ata_flush() to explicitly trigger a flush operation, and hook it
up to storage_flush() in the device shutdown path. (Flushes were
only previously used in the storage device power management path)
* After issuing all settings, re-issue IDENTIFY_DEVICE to make sure
it reflects everything we've enabled.
* Update manual section on Flash/SSD mods.

This is just to display the frequency correctly in the debug menu and prepare
for future use of said divider
Change-Id: Ib4c80ec71b3300bdf17edf6cc590229f7640d0f5
ipod6g was configured with SECTOR_SIZE of 4096, but this ATA driver
unconditionally translated these to 512B operations on the actual
storage device.
Rockbox's storage layer already has robust support for "logical sectors
larger than physical storage sectors" through use of
MAX_LOG_SECTOR_SIZE. So switch to that mechanism, allowing the ipod6g
ATA driver to be simplified.
If we want to support drives with physical sector sizes > 512B, then
we need to port the MAX_PHYS_SECTOR_SIZE logic from the primary ATA driver.
Additional changes:
* Simplify MWDMA/UDMA selection logic
* Report CE-ATA mode in debug menu
* Use LBA48 commands only if drive is over 128GiB.
* Drop default sleep/poweroff time from 20s to 7s (matching main ATA driver)
Finally, the bulk of the changes are the first phase of a badly needed
style cleanup that made reading this driver a lot harder than it should
be. I intend to split this into a separate patch.

The iPod 4g and color always ignored the very first
button press after booting, i.e. you needed to either
press another button or scroll for a bit first.
Not sure whether any other PP iPods exhibit the same
behavior, although it is not reproducible on an iPod
video.
This patch basically copies the code from FS#5230
that fixed unresponsive buttons whenever the HOLD
switch was turned off (committed as a5961c944b).

Basically, there are weak aliases for all possible IRQ handlers,
pointing at a NORETURN function. GCC complains that the aliases
don't have the same attribute, but that's actually what we want.

The flag would apparently make hardware accelerated
rendering mandatory. SDL2 will still attempt to use
hardware acceleration, if the flag is missing.

Due to the heisenberg principle, we don't want to check the battery
level when the ATA drive is "spun up".
Unfortunately some ATA devices *cough most SD adapters cough* don't
support mandatory ATA power management commands like flushing caches and
(safely) shutting down so we have to leave them "spinning".
This leads to us never updating our battery status with these
out-of-spec devices. Work around this issue by having is_active() always
return false if that's what we have.

Making line-out default output should allow detection to work
correctly. Headphone detection should work whether or not
headphone is currently the active output due to the
low impedance (relatively) of the headphones. Line-Out sinks
will likely be high impedance, so we need the output
as a pull-down for detection.
Debounce detection to prevent false triggers due to voltage swings
during playback.

The SSD detection heuristic is flawed, and when it fails
(due to very crappy CF->SD adapters) we end up corrupting things.
So let's give up a slight amount of performance on the original hard
drives (which are aging out anyway) in favor of guaranteeing safety.
