8927df4205 imx233: fix app.lds to properly support INIT_ATTR
Original fix by Marcin: it had a problem because crt0 on imx233 is more
complicated than many targets: since we use virtual memory, we first disable
the MMU, then move the entire image (including init and itext stuff), then
setup a temporary stack to setup the MMU. Only when the MMU is enabled, can
we move the init and itext stuff to its right location and finally boot.
This requires some trickery because:
- the initial move copies everything, including init and itext
- the stack overlaps with init and itext to reclaim space
- the temporary stack cannot be the same as the main stack to avoid trashing
  the init and itext code, also it needs to be a physical address

28dec004c0 Do some things to make -ffunction-sections work better.
* Add wildcards to various sections placements a la *(".text") => "*(.text*)"
* Remove hacky bits from those linker scripts (no problem encountered testing)
* Change section for asm functions from .<section> to .<section>.<function>
  so that -ffunction-sections works for those asm file too.

7d4fed53cc imx233:fuze+: major memory and usb rework
- now identity map dram uncached and have a cached and buffered virtual alias
- rework dma to handle virtual to physical pointers conversion
- fix lcd frame pointer
- implement usb detection properly
- implement bootloader usb properly
- allow the bootloader to disable MMC windowing (useful for recovery)
