On x86_64 we need CONFIG_PHYS_ADDR_T_64BIT to make the resource sizes
64bit. The kernel has this as a Kconfig variable, but on barebox sandbox
will build with whatever compiler we find, so we can't put it into Kconfig.

In the commit 40492a0c1305835c996e15eb1cce2406473ae76d
(MIPS: add common header file for DEBUG_LL via NS16550)
introduced common DEBUG_LL via NS16550 for MIPS
(see file arch/mips/include/debug_ll_ns16550.h).
In the commit 1cbe2b2c00de0efca503a983d0d008833f186f33
(MIPS: XBurst: add Ritmix RZX-50 board support)
the file debug_ll_ns16550.h used in
the file arch/mips/mach-xburst/include/mach/debug_ll.h.
Usage looks like this:
------------------------------------------------
+#ifdef CONFIG_BOARD_RZX50
+#include <mach/debug_ll_jz4755.h>
+#endif
+
+#include <debug_ll_ns16550.h>
------------------------------------------------
So after adding another board (e.g. A320) we will have something like this:
------------------------------------------------
#ifdef CONFIG_BOARD_RZX50
#include <mach/debug_ll_jz4755.h>
#endif
+#ifdef CONFIG_BOARD_A320
+#include <mach/debug_ll_jz4740.h>
+#endif
#include <debug_ll_ns16550.h>
------------------------------------------------
This approach has disadvantage:
* the files mach/debug_ll_jz4740.h and mach/debug_ll_jz4755.h
(they go to arch/mips/arch-xburst) are __BOARD-SPECIFIC__
(not SOC- or mach-specific!); The file mach-xburst/include/mach/debug_ll.h
is outside board directory, but it contains some board related information.
This commit introduce a more suitable solution.

Traditionally we call __mmu_cache_flush in early startup. There
is a problem with armv7 and hierarchical caches though, on these
systems __mmu_cache_flush uses the stack. Appearantly this was
seldomly a problem, because most of these systems have a ROM
bootloader which sets up some stack, but on a special i.MX6 system
this failed badly. We should not have to flush caches here. Every
sane system should pass control to the bootloader without stale
entries in the caches *), so it should be a safe assumption that the
cache flush can be removed.
Since __mmu_cache_flush is not called from early code anymore we can
also move it to the regular text section.
Be brave and give it a try.
*) omap3 seems to be a exception to this, but this has a cache flush
in arch_init_lowlevel already

This switches the pcm038 board to the new environment template and

This is limited board support for the Freescale P2020RDB in single CPU
mode. The DDR is configured for a memory bus running at 667Mhz.
The system boots from NOR flash and provides the console at 115200
bauds, no other drivers are included.
Finally, the PPC Kconfig and make file make the building of
the P2020RDB platform firmware possible.
