Use picasso-kernel on PAZ00

Problems left

  1. Slow data/system EXT4 format from recovery
  2. UDC usb works only if inserted before poweron
  3. Hardware video overlays freezes (Probably memory clock problem)
  4. No power button and lid events from nvec (Works with Stuw's patches)
  5. Battare uevents (Patch from 3.1 fits 3.18)

Memreserve calculations

Memory hole like kernel 3.1.10

/*
 * Carveouts for multimedia and ram console
 * 128MB - multimedia
 * 8MB - fb1
 * 16MB - fb2
 * 1MB - ram-console
 */

memory {
        reg = <0x00000000 0x20000000>;
};

/memreserve/ 0x11000000+0x9900000=0x1A900000

nvmap:0x11000000+0x8000000=0x19000000
dc1:0x19000000+0x800000=0x19800000
dc2:0x19800000+0x01000000=0x1A800000
ramconsole:0x1A800000+0x00100000=0x1A900000


memory size note

512 megabyte=536 870 912 bytes /* Total RAM */
128 megabyte=134 217 728 bytes
64 megabyte=67 108 864 bytes
32 megabyte=33 554 432 bytes

Notes

Checkout maybe this patches need to be added somehow to 3.18
