NOR requires that s_init be within the first 4KiB of the image so that
we can perform the rest of the required pinmuxing to talk with the rest
of NOR that we are found on. When NOR_BOOT is set we save our
environment in NOR at 512KiB and a redundant copy at 768KiB. We avoid
using SPL for this case and u-boot.bin is written directly to the start
of NOR.
We enclose the DMM-related parts of arch/arm/cpu/armv7/am33xx/emif4.c
with TI81xx checks as at this time U-Boot does not discard unused
sections in the main build and this code relies on functions specific to
(and only provided in) ti81xx-related code.

This patch adds support for the NOR module that attaches
to the memory cape for a Beaglebone board. This does not
add booting support; only support so that you can boot from
SD/MMC and see the NOR module so that it can be programmed.

The timer_init function is called before relocation and writes to bss data
were corrupting relocation data. Fix this by removing the call to
reset_timer_masked. The initial timer count should be 0 or near 0 anyway,
so initializing the variables are not needed.

interrupt_init also sets up the abort stack, but is not setup before
relocation. So any aborts during relocation will hang and not print out
any useful information. Fix this by moving the interrupt_init to after
the stack setup in board_init_f.

is not emulated properly by Qemu, so put a hardcoded

The timer3 counter unit for lastdesc and now values are inconsistent in current
code. The unit of "readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2)" is
second. However, CONFIG_SYS_HZ is defined as 1000 in board config file.
This means the accuracy of "lastdec" and "now" should be in millisecond,
thus fix the equation to set lastdec and now variables accordingly.
