e46fedfeb2 powerpc/85xx: introduce and document CONFIG_SYS_CCSRBAR macros
Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW
macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS.
This is necessary for the assembly-language code that relocates CCSR, since
the assembler does not understand 64-bit constants.

CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the
CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it
should not be defined in a board header file.  Similarly,
CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so
it should also not be defined in the board header file.

CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that
CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT,
and so CCSR will not be relocated.

Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot
builds (e.g. NAND) are required to relocate CCSR only during the last stage
(i.e. the "real" U-Boot).  All other stages should define
CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated.

README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

553f09823c Rename CONFIG_SYS_INIT_RAM_END into CONFIG_SYS_INIT_RAM_SIZE
CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be
some end address; to make the meaning more clear we rename it into
CONFIG_SYS_INIT_RAM_SIZE

No other code changes are performed in this patch, only minor editing
of white space (due to the changed length) and the comments was done,
where noticed.

Note that the code for the PATI and cmi_mpc5xx board configurations
looks seriously broken.  Last known maintainers on Cc:

d98b0523cf powerpc: Cleanup BOOTFLAG_* references
Now that warm booting is not supported, there isn't a need for the
BOOTFLAG_COLD and BOOTFLAG_WARM defines, so remove them.

Note that this change makes the board info bd_bootflags field useless.
It will always be set to 0, but we leave it around so that we don't
break the board info structure that some OSes are expecting to be passed
from U-Boot.

14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

d24f2d321d mkconfig: change CONFIG_MK_ prefix into plain CONFIG_
When planning for more generalization and Makefile cleanup it became
obvious that the introduction of a separate CONFIG_MK_ name space for
config options that were set through scripting in the Makefile was
not a good idea.

Originally the idea was to provide a script-free approach to supply
configuration options - there was no real need for a separate name
space. But when we now convert the existing Makefile entries to make
use of this approach, it would mean that we have to touch a large
number of board config files and add #ifdef / #define sequences to
"convert" from the CONFIG_MK_ to the CONFIG_ name space.

It seems much cleaner to get rid of this somewhat arbitrary _MK
string now for the few boards that actually use it.

dd9ca98f26 sbc8548: reclaim wasted sector in boot flash
By nature of being based off the MPC8548CDS board, this
board inherited an ENV_SIZE setting of 256k.  But since
it has a smaller flash device (8MB soldered on), it has
a native sector size of 128k, and hence the ENV_SIZE was
causing 2 sectors to be used for the environment.

By removing the unused sector, we can push TEXT_BASE up
closer to the end of address space and reclaim that
sector for any other application.  This also fixes the
mismatch between TEXT_BASE and MONITOR_LEN reported by
Kumar earlier.

Since this board also supports the ability to boot off
the 64MB SODIMM flash, this change is forward looking
with that in mind; i.e. the settings for MONITOR_LEN
and ENV_SIZE will work when the 512k sectors of the
SODIMM flash are used for alternate boot in the future.

2738bc8df6 sbc8548: allow enabling PCI via a make config option
Prior to this commit, to enable PCI, you had to go manually
edit the board config header, and if you had 33MHz PCI, you
had to manually change CONFIG_SYS_NS16550_CLK too, which was
not real user friendly,

This adds the typical PCI and clock speed make targets to the
toplevel Makefile in accordance with what is being done with
other boards (i.e. using the "-t" to mkconfig).

fdc7eb90b5 sbc8548: update PCI/PCI-e support code
The PCI/PCI-e support for the sbc8548 was based on an earlier
version of what the MPC8548CDS board was using, and in its
current state it won't even compile.  This re-syncs it to match
the latest codebase and makes use of the new shared PCI functions
to reduce board duplication.

It borrows from the MPC8568MDS, in that it pulls the PCI-e I/O
back to 0xe280_0000 (where PCI2 would be on MPC8548CDS), and
similarly it coalesces the PCI and PCI-e mem into one single TLB.

Both PCI-x and PCI-e have been tested with intel e1000 cards
under linux (with an accompanying dts change in place)

11d5a629f8 sbc8548: correct local bus SDRAM size from 64M to 128M
The size of the LB SDRAM on this board is 128MB, spanning CS3
and CS4.  It was previously only being configured for 64MB on
CS3, since that was what the original codebase of the MPC8548CDS
had.  In addition to setting up BR4/OR4, this also adds the TLB
entry for the second half of the SDRAM.

9b3ba24f18 sbc8548: enable access to second bank of flash
The sbc8548 has a 64MB SODIMM flash module off of CS6 that
previously wasn't enumerated by u-boot.  There were already
BR6/OR6 settings for it [used by cpu_init_f()] but there
was no TLB entry and it wasn't in the list of flash banks
reported to u-boot.

The location of the 64MB flash is "pulled back" 8MB from
a 64MB boundary, in order to allow address space for the
8MB boot flash that is at the end of 32 bit address space.
This means creating two 4MB TLB entries for the 8MB chunk,
and then expanding the original boot flash entry to 64MB
in order to cover the 8MB boot flash and the remainder
(56MB) of the user flash.

7b1f1399e8 sbc8548: delete unused MPC8548CDS info carried over from port
There are a couple defines and PCI bridge quirks related to the PCI
backplane of the MPC8548CDS that have no meaning in the context of
the port to the sbc8548 board, so delete them.

Also, the form factor of the sbc8548 is a standalone board with a
single PCI-X and a single PCI-e slot.  That pretty much guarantees
that it will never be a PCI agent itself, so the host/agent and root
complex/end node distinctions have been removed.

Similarly, since there is no physical connector mapping to PCI2, so
all references of PCI2 in the board support files have been removed
as well.
