Remove the troublesome union hob_pointers so that some annoying casts
are no longer needed in those hob access routines. This also improves
the readability.

Introduce a gd->hose to save the pci hose in the early phase so that
apis in drivers/pci/pci.c can be used before relocation. Architecture
codes need assign a valid gd->hose in the early phase.
Some variables are declared as static so change them to be either
stack variable or global data member so that they can be used before
relocation, except the 'indent' used by CONFIG_PCI_SCAN_SHOW which
just affects some print format.

On x86, some peripherals on pci buses need to be accessed in the
early phase (eg: pci uart) with a valid pci memory/io address,
thus scan the pci bus and do the corresponding resource allocation.

Since commit 41623c91b0 u-boot running in qemu is
crashing in function do_omap3_emu_romcode_call(). RX-51 board uses this function
for Cortex-A8 errata 430973 workaround (Set IBE bit in ACR) which is needed only
on real secure device and not in qemu.
This board patch just disable calling secure PPA routine on non secure devices.
Qemu implements GP device and with this patch u-boot is working in qemu again.

When CONFIG_TRACE is disabled, linking fails with:
common/built-in.o:(.data.init_sequence_f+0x8): undefined reference to `trace_early_init'
To fix, wrap trace init calls with #ifdef CONFIG_TRACE.
While at it, remove the static inline version of the init call from
trace.h as suggested by Simon Glass, since it doesnt work.

MetaWare debugger (MDB) is still used as a primary tool for interaction
with target via JTAG. Moreover some very advanced features are not yet
implemented in GDB for ARC (and not sure if they will be implemnted
sometime soon given complexity and rare need for those features for
common user).
So if we're talking about development process when U-Boot is loaded in
target memory not by low-level boot-loader but manually through JTAG
chances are high developer uses MDB for it.
But MDB doesn't support PIE (position-independent executable) - it will
refuse to even start - that means no chance to load elf contents on
target.
Then the only way to load U-Boot in MDB is to fake it by:
1. Reset PIE flag in ELF header
This is simpe - on attempt to open elf MDB checks header and if it
doesn't match its expectation refuces to use provided elf.
2. Strip all debug information from elf
If (1) is done then MDB will open elf but on parsing of elf's debug
info it will refuse to process due to debug info it cannot understand
(symbols with PIE relocation).
Even though it could be done manually (I got it documented quite a while
ago here http://www.denx.de/wiki/U-Boot/ARCNotes) having this automated
way is very convenient. User may build U-Boot that will be loaded on
target via MDB saying "make mdbtrick".
Then if we now apply the manipulation MDB will happily start and will
load all required sections into the target.
Indeed there will be no source-level debug info available. But still MDB
will do its work on showing disassembly, global symbols, registers,
accessing low-level debug facilities etc.
As a summary - this is a pretty dirty hack but it simplifies life a lot
for us ARc developers.

Currently, "nand scrub" runs chip->scan_bbt at the end of
nand_erase_opts() even if NAND_SKIP_BBTSCAN flag is set.
It violates the intention of NAND_SKIP_BBTSCAN.
Move NAND_SKIP_BBTSCAN flag check to nand_block_checkbad() so that
chip->scan_bbt() is never run if NAND_SKIP_BBTSCAN is set.
Also, unset NAND_BBT_SCANNED flag instead of running chip->scan_bbt()
right after scrub. We can be lazier here because the BBT is scanned
at the next call of nand_block_checkbad().

Commit 35c204d8a9 (nand: reinstate lazy bad block scanning)
broke NAND_BBT_USE_FLASH feature.
Its git-log claimed that it reinstated the change as by commit
fb49454b1b ("nand: reinstate lazy bad block scanning"), but it moved
"chip->options |= NAND_BBT_SCANNED" below "chip->scan_bbt(mtd);".
It causes recursion if scan_bbt does not find a flash based BBT
and tries to write one, and the attempt to erase the BBT area
causes a bad block check.
Reinstate commit ff49ea8977 (NAND: Mark the BBT as scanned prior to
calling scan_bbt.).

Boot from SD-card (and probably also from NAND) was broken since
commit d6d07a9bec ("arm: vf610: add NAND support for vf610twr").
It looks like the increased size of U-Boot lead to a situation
where the boot ROM overwrote its own stack/heap while loading
U-Boot from the SD-card to the SRAM. However, U-Boot worked fine
when loaded through USB serial loader directly into SRAM. It
looks like loading from SD-card uses other stack/heap location
then the serial loader (or maybe no stack or heap at all).
This fix moves U-Boot to gfxRAM, which is 512kB in size and is not
used by the boot ROM nor the SD-card loader of it.
