041d42e789 OMAP3: workaround for ARM Cortex-A8 erratum 725233
725233: PLD instructions executed with PLD data forwarding
enabled can result in a processor deadlock

This deadlock can happen when NEON load instructions are used together
with cache preload instructions (PLD). The problematic conditions
can be triggered in-the-wild by NEON optimized functions from pixman
library (http://cgit.freedesktop.org/pixman), which perform dynamic
adjustment of prefetch distance.

The workaround disables PLD data forwarding by setting PLD_FWD bit
in L2 Cache Auxiliary Control Register as recommended in ARM Cortex-A8
errata list.

The deadlock can only happen on r1pX revisions of Cortex-A8 (used in
OMAP34xx/OMAP35xx). Performance impact of the workaround is practically
non-existant.

gcc has to zero out it, and some gcc versions optimize this with
an implicit call to memset. Move definition to data section
to avoid that (it has also nice side effect that we need not

c7de810c79 allow MCF532x to use CONFIG_MONITOR_IS_IN_RAM
CONFIG_MONITOR_IS_IN_RAM is broken for MCF532x. This patch fixes this
 by conditionally
- removing the vector table at the beginning of code
- not overwriting the vector base register
- removing the code to re-set the PLL, which effectively disables
  SDRAM access

fe389da6ae mpc83xx: fix out-of-tree mpc8315 nand build
commit 2e95004deb "mpc83xx: Add NAND boot support
for MPC8315E-RDB boards" symlinked nand_spl/board/freescale/mpc8315erdb to
mpc8313erdb in order to not duplicate code.

Since the main makefile builds nand_spl/board/$(BOARDDIR) (which makes sense),
and the board Makefile and linker script are the only two necessary files
to enable out-of-tree building, and other boards have duplicated nand makefiles
(e.g. 8536ds & 8569mds), it only seems prudent to copy these two files in the
name of the 8315 too.
