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.

Using the audio buffer directly is a bad idea because this will
render core_alloc non-functional if load_firmware() writes into
the buffer but then fails, for example on a checksum mismatch.

The implementation of write_bootdata() and get_redirect_dir() was
copied verbatim in two different places, obviously a bad thing for
maintainability. This moves them to a new file multiboot.c as they
are only used for multiboot.

This looks like it was copy-pasted blindly from elsewhere and it

The header format is basic, a variable length list of values
tagged by 4-byte strings. The main application to to allow a
loader to determine the load address of the binary at runtime
instead of using a hardcoded address. But the header contents
aren't fixed and it could be extended for other purposes too.

Provide definitions for the macros:
* RB_ROOT_VOL_HIDDEN(v) to exclude certain items from the root.
* RB_ROOT_CONTENTS to return a string with the name of the
directory to mount in the root.
Defaults are in export/rbpaths.h
It's a bit much for those that don't need the full functionality.
Some conditional define can cut it back a lot to cut out things only
needed if alternate root mounts are required. I'm just not bothering
yet. The basic concept would be applied to all targets to keep file
code from forking too much.

This kind of reverts 7b596416bf ("Gigabeat S: Update RDS processing to
use asynchronous I2C rather than thread."). However, requiring RDS to
run in thread context will a) allow more upcoming features and b) remove
quite some complexity from the codebase (see the diffstat here) because
Gigabeat is the only user. iMX31 should be able to handle one more
thread, as it can even run Linux.

The OST prescaler bugfix (7a5130a277) broke runtime switching
between 1.0V and 2.0V modes. The 1ms delay after shutting down
the DAC isn't long enough to reset it, so it gets stuck in the
power mode assigned at boot. Change the delay back to 4ms, the
effective value prior to the OST bugfix.

use si4700_read() instead of si4700_read_reg() to make it clear we are
not interested in the register itself but in the cache update. Also, a
tiny bit more efficient as we save a function call and don't request a
return value we don't use anyhow.

Recording works now, although I'm sure there will be a few
things that need fine-tuning. A major issue is that writing
to the SD card creates noticable interference, which happens
on the original firmware too but seems worse under Rockbox.
(Since Rockbox waits until RAM fills up before writing data,
the interference will only be heard on >50 MiB recordings.)

This caused LCD problems on the ErosQ, where the screen would
go white until being put through a sleep/wake cycle. The exact
reason for this isn't obvious, but the problem didn't exist
prior to the AXP driver rewrite.
The two dependent changes,
42999913ba - x1000: Increase USB current limit to 500 mA at all times
90dd2f84a9 - x1000: Correctly limit USB charging current
ended up bringing the USB charging situation back to where it
was prior to the rewrite, so the cleanest option is to revert
the whole lot.
This reverts commit 42999913ba.
This reverts commit 90dd2f84a9.
This reverts commit 2d89143962.

The 100 mA USB current limit added in commit 90dd2f84a9
is a problem when booting with a completely dead battery.
Often 100 mA isn't enough to power the player, never mind
charge the battery, so revert to the old behavior of only
limiting charge current.
Given that the original firmware on these devices isn't
following the USB spec to the letter, it's probably not
worth trying to make Rockbox do so unless and until it
causes a real problem - which hasn't happened yet.

This problem actually had nothing to do with USB boot; it's
because the cable is plugged in when the USB mode menu item
is selected. The USB thread detected the select button press
and went into charge-only mode (as it usually does when you
hold down a key in Rockbox). This is fixed by having the USB
thread ignore most keys in the bootloader.
USB connect events are delivered via the button queue, and
there were also cases where the connection could be missed
if the event happened within another UI screen. This should
also be fixed.

The way this was done before was wrong - limiting the charge
current is not enough since the device will draw additional
power to run. Use the AXP192's vbus current limit control to
stay compliant with the USB specification.
