PATCH v7 1/1 AT91SAM9*: Change kernel address in dataflash to match u-boot's size

On at91sam platforms, u-boot grew larger than the allocated size in dataflash, the layout was:

bootstrap  0x00000000
ubootenv   0x00004200
uboot      0x00008400
kernel     0x00042000
fs         0x00252000

u-boot with the defconfig doesn't seem to fit in 0x42000 - 0x8400 = 0x39C00 bytes anymore.

Now, the layout is:

bootstrap  0x00000000
ubootenv   0x00004200
uboot      0x00008400
kernel     0x00084000
fs         0x00294000

Changes for v2:
- changed the layout as per Marek's recommendation Changes for v3:
- prefixed the patch title with AT91SAM9*:
Changes for v4:
- changed the layout again as per Ulf Samuelsson's request:
http://lists.denx.de/pipermail/u-boot/2012-February/118988.html
Changes for v5:
- also update partition list
Changes for v6:
- rebase on latest u-boot-atmel
Changes for v7:
- Still allocate 0x00210000 for the kernel

PATCH v7 1/1 AT91SAM9*: Change kernel address in dataflash to match u-boot's size

Dear Alexandre Belloni,

Quoted 11 lines · Alexandre Belloni

On at91sam platforms, u-boot grew larger than the allocated size in dataflash, the layout was:
bootstrap  0x00000000
ubootenv   0x00004200
uboot      0x00008400
kernel     0x00042000
fs         0x00252000
u-boot with the defconfig doesn't seem to fit in 0x42000 - 0x8400 = 0x39C00 bytes anymore.

Quoted 8 lines

Now, the layout is:
bootstrap  0x00000000
ubootenv   0x00004200
uboot      0x00008400
kernel     0x00084000

applied to u-boot-atmel/master, thanks!
