Waitstates for flash. The default value is suitable for the
standard flashes used in axis products (120 ns).

Waitstates for CSP0-3. 0 is a good choice for most Axis products.
It may need to be changed if external devices such as extra
register-mapped LEDs are used.

SDRAM configuration for group 0. The value depends on the
hardware configuration. The default value is suitable
for 32 MB organized as two 16 bits chips (e.g. Axis
part number 18550) connected as one 32 bit device (i.e. in
the same group).

SDRAM configuration for group 1. The default value is 0

described in the help for SDRAM_GRP0_CONFIG.

SDRAM timing parameters. The default value is ok for
most hardwares but large SDRAMs may require a faster
refresh (a.k.a 8K refresh). The default value implies
100MHz clock and SDR mode.

SDRAM command. Should be 0 unless you really know what
you are doing (may be != 0 for unusual address line
mappings such as in a MCM)..

Configures the direction of general port A bits. 1 is out, 0 is in.
This is often totally different depending on the product used.
There are some guidelines though - if you know that only LED's are
connected to port PA, then they are usually connected to bits 2-4
and you can therefore use 1c. On other boards which don't have the
LED's at the general ports, these bits are used for all kinds of
stuff. If you don't know what to use, it is always safe to put all
as inputs, although floating inputs isn't good.
