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
NAK!
1. You need to be aware of the page size of dataflashes.
Each page is 1056 bytes, not 1024 bytes.
Your patch will make the U-Boot image start in the middle of a page.
2. Std AT91bootstrap loads U-Boot from 0x8400
so your patch breaks 99% of all SAM9 boards.
If you want to grow U-Boot, then
bootstrap 0x00000000 ; 16 kB
ubootenv 0x00004200 ; 16 kB - Should be plenty
uboot 0x00008400 ;
kernel 0x00063000 ; Why waste space...

Changes for v2:
- changed the layout as per Marek's recommendation
Changes for v3:
- prefixed the patch title with AT91SAM9*:
