configs: at91sam926* use latest u-boot and mainline linux

While upgrading the configs, it proved necessary to make more space on
the dataflash for u-boot since it grew because of relocation.

dataflash is then repartitionned to make more room for u-boot and a redundant
environment.

+Every AT91SAM plaforms were broken between 2010.12 and 2011.03 because
+of the relocation changes.
+
+We have to get JUMP_ADDR consistant with what is used by u-boot
+(CONFIG_SYS_TEXT_BASE).
+
+I didn't know what to do with at91sam9m10g45ek as it doesn't seems to be
+converted yet. But anyway, that means that it is either not working or
+doesn't care so changing it here shouldn't harm.
+
+I also chose to "repartition" the dataflash. u-boot is now living at
+0x4000, letting 16kB for the bootstrap. We also have to increase the
+IMG_SIZE as u-boot as grown larger than the default value.
+As requested on the u-boot ML, we assume that it could be up to 512kB
+big.
+
+It means that now, you have to flash your kernel at 0x0008C000 instead
+of 0x00042000. And so you also have to load it from that adress from
+u-boot.
+
+Then, remember that you could decrease IMG_SIZE to boot faster.

+Subject: [PATCH] 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
+
+u-boot with the defconfig doesn't seem to fit in 0x42000 - 0x8400 =
+0x39C00 bytes anymore.
+
+Now, the layout is:
+bootstrap  0x00000000
+uboot      0x00004000
+ubootenv   0x00084000
+ubootenv2  0x00088000
+kernel     0x0008C000
+
