Avoid startup code clashing with the .init section, which is
by convention used for INIT_ATTR code that can be discarded
after app initialization.

Get the linker to automatically assign load addresses for

This flash chip is found on some Surfans F20 units. For our purposes
it's the same as the GD5F1GA4xExx so just #define an alias instead of
adding a whole new chip struct.

The bootloader backup is intentionally simple, but it's a little
*too* simple. Add a sanity check to make sure what we're backing
up or restoring contains the first 8 bytes of the SPL header.
This isn't going to catch all possible problems, but it'll stop
obviously non-functional backups from being restored.

Merge the x1000 and jz47xx exception handling code since they use
the same exception vectors and handlers. The interrupt handler is
now called from the common exception vector, but remains separate
for each board since they have different IRQ layouts.
The new exception handler can provide a stack traceback from the
interrupted code, rather than the (uninteresting) caller traceback
displayed by panicf. This allows you to see what led up to a null
pointer deref or division by zero, which makes it _much_ easier to
track down errors that occur in common leaf functions like strcmp.

Instead of putting "#ifdef LCD_STRIDEFORMAT" at every usage of the
macro it's simpler to have config.h define LCD_STRIDEFORMAT to the
default of horizontal stride when the target leaves it unspecified.

This is another chip used in newer Surfans F20 units. Like the
Winbond chip, it's a 1-gigabit chip with on-die ECC. Notably it
has an expanded 128-byte OOB area that is only accessible when
on-die ECC is disabled.

This chip is apparently used in some Surfans F20 units, and has
the same geometry as the ATO25D1GA. It has an on-die ECC engine.

Decouple chip IDs from chips, and allow the chip ID table to list
which read ID method should be used. Use a safe controller setup
during identification instead of using the first chip's parameters.

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

Use per-function sections to avoid linking in x1000_boot_linux()

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.

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.

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.

Enables multiboot for the FiiO M3K, Shanling Q1, and Eros Q native port.
Note this requires an up-to-date Rockbox _and_ bootloader.

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.

Calling multiple levels of indirection in a loop slows things down
Really these need to be rewritten to take a start and end address
like most of the rest of the codebase
But this is safer without having test hardware in hand

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).

Two helpers (_init_clocktree and _init_uart2) already existed in
the SPL and are copied verbatim from there. The SPL versions are
still present and will be removed when dual boot works from the
main bootloader.
The other two helpers (_cleanup and _load_pdma_fw) are new.
