[U-Boot] [PATCH 0/1] versatile/vexpress: board configs: Use buffered writes on Flash

[Jagannadha Sutradharudu Teki]

Current writes on nor flash uses normal flash write calls
due to this writing to NOR is very slow, 
so I was enabled buffered writes and tested on QEMU.

Regards,
Jagan.

[U-Boot] [PATCH 1/1] versatile: board configs: Use buffered writes on flash

[Jagannadha Sutradharudu Teki]

This patch provides a support to use buffered writes on flash
for versatile and vexpress boards.

This will certainly increase the flash writes.
