As usual, here is an update with what was done today:
* Fixed USB, now it is possible to boot_usb a kernel with BP in normal
mode.
* Fixed the MMC driver so it does not freeze the 2.4 kernel when loaded
from MMC.
* Increased MMC clock from 0.3 to 5 Mhz.
* Doesnt turn on the backlight when the default boot is done (also
fixes the backlight turning on when the battery is inserted)

No additions to the todo list today.
A preview version is available at [1]. I dont recommend anybody to
flash it yet, but i encourage people to test it with different microSD
cards and report the results.
Here is a 6 step quick guide..
1. Edit boot_usb.c, s/pxa_code, pxa_code_s/NULL, 0/ for your phone
entry on phonetypes[]. Rebuild.
2. Setup the _first_ partition of your microSD to FAT(16|32)
3. Create a "/boot/menu.lst" file:
# menu.lst
title Motorola 2.4
kernel /boot/default
param not supported yet
title OpenEZX
kernel /boot/openezx
param not supported yet
4. Dump a 2.4 kernel from the original flash, or get one somewhere and
put it on /boot/default
5. *Build an OpenEZX kernel, get the machid-magic[2] and
'cat machid-magic OpenEZX-kernel > bootable-kernel'. Put the
bootable-kernel on /boot/openezx*
6. Send gen-blob[1] with the boot_usb built above.
Usage:
Hold the following key when sending via boot_usb (or powering on when
flashed).
Scroll Down (volume -): Boot menu
Scroll UP (Volume +): USB
Not holding any key boots /boot/default without any FB activity.
*The above guide is valid for all phones, but on e2, e6, e680, a910
gen-blob will not recognize any keys, or will not be able to read the card*
*The preview[1] was not flashed on A1200, it was tested on flash
(kernel partition, 0x00020000) only on a780.*
The (chaotic) source code is on svn.openezx, if somebody wish to help
me with the TODO list or code clean-up. :)
