The flash bank name is a required element in adding flash banks,
however other than looking at the config file there is no way of
getting the name used in openocd.

the unprotect fn in stm32 needs to unprotect more sectors
than was requested aligned to some boundary.
Print warning when this happens.

Some flash's do not support buffer writes, so we now check
they are supported before trying to use them.

The existing code used incorrect timeout values for the various cfi
operations. We now calculate the timeouts and convert to
msecs if necessary.

If flash chip is not listed in the table, or if no flash is
connected, pointer must be properly initialized.

flash programming via flash write_image or gdb load would
produce a bogus error message that the flash chip was to
small.
The solution is to limit the current flash programming
run to the current chip.

SMI interface hides the real SPI bus between SPEAr and
external flash.
Added comments to highlight the SPI operation, to help a
future rework in SPI generic and SPEAr specific drivers.

Add comments to assembly flash loader for STM32. Add tiny improvement in
size of the algorithm (40 vs 48 bytes) and tiny speed improvement (~1.5%,
as time is wasted on waiting for end of operation anyway).
