Scaffolding for a port, starting from the rk27xx generic target: configure
entry 146 (target id 117, model number 132), config/samsungypcp3.h, and
firmware/target/arm/rk27xx/ypcp3/.
- LCD: the rk27xx LCD interface (lcdif-rk27xx.c) with this panel's init
sequence, from RE. See g#1050. Looks like SPFD5420A 18-bit bus,
400x240 landscape. It differs from the generic panel's sequence in the
gamma curve and in not writing VCOM_HV1.
- Backlight: PD4 / PWM0 with the generic board's timing, which the hwstub
work found to be the same.
- Storage: the microSD slot. Card detect is PC7, active low,
as on the generic board.
- Keys: the YP-R0's key set - five-way yog, Back, Menu, Rec/User, Power -
so the target uses SAMSUNG_YPR0_PAD and its keymaps. Eight keys sit on
two resistor ladders on the LSADC, found in the original firmware and
measured on a unit:
channel 1 up 158, down 295, select 435, left 561, right 687
channel 2 menu 155, back 292, user 431
each key owning half a step either side of its reading;
power is GPIO C1, active high.
Builds as firmware and as bootloader. Status 3 (unusable) in builds.pm.

Rockbox only drives NAND parts proven on hardware, and this tree has one
model to prove them on. This is the image that lets an owner of another
Nano 3G supply what validating theirs takes: a bootloader built with
-DNAND_CHECK and run from DFU, which never touches the NOR flash or
writes to the NAND.

The Nano 3G keeps everything behind the S5L8702 flash controller and
Apple's FTL ("Whimory"), and nand-nano3g.c was a stub, so the port had
no storage at all. This is the flash driver, the FTL and the wiring that
makes the NAND Rockbox's disk. The three are one change because neither
half is usable without the other: the driver alone cannot see a
filesystem, and the FTL alone has nothing to drive.

Most of the churn here occurs because 'filesize' is one of
the redefined filesystem functions, but some of the structs
used by the native FS code also include a 'filesize' member
variable which gets renamed by the macro in some but not all
source files.
It's easier to rename 'filesize()' to 'ffilesize()' rather
than try to clean up the macro mess or renaming the struct
members.
There is weirdness with root_realpath() which now breaks on
native builds because it was assumed to be unprefixed there.
dir_get_info() was unprefixed everywhere but this just seems
inconsistent; make it follow the FS_PREFIX() convention too.

Pure file move, in preparation for a second Ingenic SoC.
dma, gpio, i2c, installer, kernel, nand and the SPL NAND backend
move from target/mips/ingenic_x1000/ to target/mips/ingenic/
Drivers that cannot move as whole files, because part of each is
genuinely X1000-specific, are left alone for now: msc, uart, sfc, the
debug menu and the OST helpers in system-x1000.c.
Verified as a no-op: built at target 246 --type=b before and after from
the same source path, bootloader.bin is byte-identical, and every moved
file's object has the same instruction stream under its new name.
Builds clean with no warnings for targets 246, 260 and 247, both
--type=n and --type=b.

Both targets were part of the (presumably dead) Lyre project
and no longer build. The Mini2440 was much more complete than
the Lyre and doesn't seem terribly difficult to fix up to the
point where it at least builds, if someone still cares -- but
given it is a dev board in a box, it's unlikely it ever saw
much use.

Add a 'make start' target which starts Rockbox using a
debugger. This only works to load the main binary, but
makes it much faster to test changes that don't affect
plugins/codecs.
Because SDRAM isn't accessible at reset and the main
binary is usually too big to fit in SRAM, the bootloader
must be flashed first before Rockbox can be loaded in
this way.
The boot protocol involves GDB writing a check pattern
to SRAM while the CPU is held in reset. The bootloader
detects the pattern and takes a breakpoint, by which
time SDRAM is accessible; GDB can then upload a binary
ELF image (copied as a raw file, since the ELF will be
loaded using RB's ELF loader) and leave the breakpoint
to continue booting.
From there the bootloader can load the ELF binary from
memory, exactly like a normal SD card boot.
Change-Id: I4eb971b4162ea422e38660455cfa0958cefaa18d
To avoid problems with SDMMC DMA not being able to
access all SRAMs equally, the ELF binary is loaded
at the top of SDRAM and then copied into place.

On the Echo R1, the main regulator is enabled primarily by
the power button and USB input, and secondarily by the CPU's
own output pins (cpu_power_on signal or RTC alarm output).
From a user perspective, the player should appear to power
up and down only if the power button is long pressed, which
must be implemented in software. These logical power states
are called "active" and "inactive" in the bootloader.
Going from inactive to active will attempt to boot Rockbox
unless a button (d-pad down) is held to enter bootloader
USB mode instead. Going from active to inactive will shut
down the player. The bootloader will also automatically
shut down after a short timeout, if USB is not plugged in.
In the inactive state, the player is supposed to enumerate
over USB so it can negotiate a charging current, but should
otherwise appear "off". In particular it shouldn't expose
mass storage or even power up the SD card, nor power up the
LCD/backight. This isn't implemented yet, because there's
no way to dynamically change USB configurations (eg. going
from active to inactive should trigger re-enumeration to
switch to charge only mode). To avoid surprising behavior,
the bootloader will just boot Rockbox immediately if USB is
plugged in at boot.

Early 6th gen ipods (80GB and 160GB "fat") are limited to LBA28
which results in a hard upper limit of 128GiB on the storage size.
The later 120GB model also shares this limitation. These are identified
by HwVr of 0x00130000 and 0x00130100, respectively.
The final revision of the iPod Classic series (160GB "thin") does not
have this limitation, and can be identified by a HwVr of 0x00130200 or
0x00130300.
This is strictly an issue with Apple's stock firmware, and not the
hardware, and Rockbox will happily utilize the full capabiltiies of any
installed storage device. Unfortunately, if you boot into the stock
Apple firmware, said firmware will destructively trash the partition
table and filesystem.
Consequently, the Rockbox bootloader will now check if the installed
drive requires LBA48, making sure the flashed firmware also supports
LBA48. If not, we will disallow booting into the OF (including disk mode)
altogether. This check can be overridden by holding down LEFT, at which
point you get to keep all the pieces.
Note: While Apple never released firmware without these limitaitons on
the older models, there is a way to update to update these to the newer
firmware. This requires altering the stored HwVr, so it is safe to use
the HwVr as a proxy for the installe firmware capabilities.

We used 16-bit variables to store the 'character code' everywhere but
this won't let us represent anything beyond U+FFFF.
This patch changes those variables to a custom type that can be 32 or 16
bits depending on the build, and adjusts numerous internal APIs and
datastructures to match. This includes:
* utf8decode() and friends
* font manipulation, caching, rendering, and generation
* on-screen keyboard
* FAT filesystem (parsing and generating utf16 LFNs)
* WIN32 simulator platform code
Note that this patch doesn't _enable_ >16bit unicode support; a followup
patch will turn that on for appropriate targets.
