The L1 D-cache on e6500 is write-through. This means that it's not
considered a good idea to have the L1 up and running if the L2 is
disabled. We don't actually *use* the L1 until after the L2 is
brought up on e6500, so go ahead and move the L1 enablement after
that code is done.

This timer runs at a rate that can be calculated, well over 100MHz. It is

Commit 18652864 (Introduce generic link
section.h symbol files) changed the __bss_end symbol type from char[] to
ulong. This led to wrong relocation parameters which ended up in a not working
u-boot. Unfortunately this is not clear to see cause due to RAM aliasing we
may get a 'half-working' u-boot then.

Fix this by dereferencing the __bss_end symbol where needed.

Microblaze uses gpio which is connected to the system reset.
Currently gpio subsystem wasn't used for it.

via gpio subsystem.

There are various configurations which Microblaze can have
that's why gpio_alloc/gpio_alloc_dual(for dual channel)
function has been introduced and gpio can be allocated
dynamically.

Adding several gpios IP is also possible and supported.

For listing gpio configuration please use "gpio status" command
