There is actually no need to parameterize most commands with row
or column cycles, usually the opcode and row/column address width
are linked. When this is not the case we can use raw SFC commands
or define new macros.

Using predefined commands is too inflexible so allow the chip data
to specify I/O commands directly.

The iPod classic/6G comes with 64MB of RAM. This
brings it in line with the plugin buffer size of some
other targets that have the same amount of RAM,
such as the Fiio M3K, and enables the use of
PictureFlow for users with very large databases.

Use per-function sections to avoid linking in x1000_boot_linux()
on normal builds, which prevents link errors due to referencing
a non-existent usb_close().

Many SPI NAND flash chips have on-die ECC engines that report
ECC status via the status feature register. This code handles
the common case where ECC status is reported with 2 bits: one
bit to indicate if flips were detected & corrected, and another
bit to indicate an uncorrectable error.

Using 'typedef struct' is not in line with the project coding style

If the USB controller is active when we hand over to Linux it'll
often trigger "irq nobody cared" warnings. Disabling the controller
before boot prevents that.
Also move the USB PHY bit workaround from the dualboot cleanup hook
to the main Linux boot function. Mainline kernels don't clear these
bits either.

Define common functions for loading 16/32/64-bit unsigned integers
with big, little, or host endianness, and distinguishing unaligned
and aligned cases.
Unaligned loads are supported generically by default, but this can
be overridden with a more efficient implementation on architectures
which support unaligned loads natively.

USB ask mode is basically a footgun: it can't work on native targets
and doesn't work reliably on hosted ones, and it continually produces
a slow trickle of problems. FS#13317 gives a rundown of the issues.
Removing the setting seems like the best solution for now, since a fix
would be pretty involved.
This partially reverts 60f581e8f5. The USB Mode setting is left in
place so the option can be added back later in a non-buggy way.

Left shifts are not defined in C if they would cause signed overflow,
so these expressions get instrumented, which makes them unusable as
switch values and triggers compile errors when compiling with UBSan.

flags were getting un-initialized memory
it really didn't matter with the flags getting initialized
anyway
But once I added a new flag that didn't explicitly
set or clear the flag at init well here we are
set flags to VP_DEFAULT_FLAGS in viewport_set_defaults()
add the flags variable to the default vp's set to 0
(it was already initialized to 0 by bss, make it explicit)

Allow a clean shutdown to end in either power off or reboot. Add a
new event SYS_REBOOT to signal it and sys_reboot() to trigger the
event. SYS_REBOOT signals a reboot request and should be listened
for alongside SYS_POWEROFF events.

MEM_ALIGN_ATTR should take advantage of cache line alignment on
all native CPUs which define it, not just ARM CPUs. (This could
arguably be done for hosted targets too, but we don't necessarily
know the size of a cache line there.)

Hold "Play" to boot the OF, or boot it from the recovery menu
by holding "Vol. Up". If you had the hosted port installed on your
player before installing the native port, you'll still have to go
through the hosted bootloader.
A couple notes:
- When booting from the menu, the recovery menu disappears, then
reappears before going into the OF.
- You need to hold the play button for like a half second after the
blue light comes on in order to get into the OF.
The recovery appears to be there, but it doesn't seem to be intended
for end users - it just says "Updater V1.1 - Insert TF Pls". I haven't
tested it beyond seeing that it boots, so I'm going to comment it out
for now.

This gets the volume that the path eventually refers to by parsing
the last volume specifier and returning the part of the path after
it (which does not contain any volume specifiers). The initial part
of the path therefore contains everything up to and including the
last volume specifier.

Enables multiboot for the FiiO M3K, Shanling Q1, and Eros Q native port.
Note this requires an up-to-date Rockbox _and_ bootloader.
Usage instructions will (eventually) be found on the wiki:

Searching in volume 0 is necessary for multiboot targets with only
one drive, like the M3K/Q1/ErosQ. Without this the search code will
never look at the redirect file on these targets.
The search bound is configured with a setting MULTIBOOT_MIN_VOLUME,
which defaults to 0, but is defined to 1 for Sansa players so they
keep their old behavior.

There should be no need for any compatibility hacks since this
value was mostly used internally between the SPL and bootloader.
clk_init() was the only user in the main Rockbox binary which
accessed it, but when loaded by the Rockbox bootloader that code
will not be reached since BOOT_FLAG_CLK_INIT is already set.

Basically, there's longstanding bug in Linux with self-extracting
kernels on MIPS which just happened to manifest now on the M3K as
a hang on boot. The fix is applied to the M3K and Q1 since they
both use this type of kernel image.

Replace inline section copy/fill loops with subroutines, which
reduces code size a bit and and handle zero size copies properly.
Remove the cache initialization loop as well. There's no actual
reason for this because the SPL initializes the caches and just
dropping the cache can even be harmful (in this case it wasn't,
because the SPL flushes the whole cache right before calling in).
