The purpose of this serie is to clean the mpc8xx code a bit prior to moving
to OF and DM model.
Christophe Leroy (15):
powerpc, 8xx: initialisation global data
board, MCR3000: replace mtd->priv by mtd_to_nand()
board, MCR3000: Increase Monitor size
soft_i2c: cleanup - no mpc8xx support
boards: MCR3000: cleanup config
powerpc: mpc8xx: cleaning up watchdog
powerpc: mpc8xx: make get_immr() independent of CONFIG_8xx
powerpc: mpc8xx: Change CONFIG_8xx to CONFIG_MPC8xx
powerpc: 8xx: get rid of the multiple PVR_ values
powerpc: mpc8xx: refactorise reginfo
powerpc: mpc8xx: harmonise initialisation of the immap local pointer
powerpc: mpc8xx: remove get_immr() argument
powerpc: mpc8xx: use PVR related defines and macros
common/env_embedded: allow fine placement of environment object
board: MCR3000: Use smaller flash sector for environment
Changes since v2:
Cleaning more items in patch 5
Not removing get_immr() anymore in patch 7
Patches from 11 are new in this version

Some config is redundant with Kconfig. Fix it.
Also remove unused configs
Move SDRAM_MAX_SIZE in the only place it is used
include/environment.h already defines CONFIG_ENV_SIZE
from CONFIG_ENV_SECT_SIZE and defines CONFIG_ENV_ADDR as
(CONFIG_SYS_FLASH_BASE + CONFIG_ENV_OFFSET)

In preparation of migration to DM watchdog, clean up a bit.
The 8xx watchdog really is a HW watchdog, so declare it as is
then it goes through Kconfig

SPRN_IMMR is defined regardless of the CPU. Therefore, there
is no point in enclosing get_immr() inside a #ifdef CONFIG_8xx
As it a static inline function, it will in any case only be
compiled in functons using it.

CONFIG_8xx doesn't mean much outside of arch/powerpc/
This patch renames it CONFIG_MPC8xx just like CONFIG_MPC85xx etc ...
It also renames 8xx_immap.h to immap_8xx.h to be consistent with
other file names.

None of those values are used at the time being.
Just keep one and call it PVR_8xx

reginfo is redundant with some of the commands in immap.c, so
move reginfo into that file and remove duplicated info.

In most places, immap local pointer is defined as
immap_t __iomem *immap = (immap_t __iomem *)CONFIG_SYS_IMMR;
In a few places, it is defined as
immap_t __iomem *immap = (immap_t __iomem *)(immr & 0xFFFF0000);
This patch replaces the few of the latest form by the other one.
The two are fully equivalent since SPRN_IMMR is set with CONFIG_SYS_IMMR
very early in start.S

get_immr() is always called with 0 as an argument, so it is useless.

Commit 7653942b10e9e ("common/env_embedded.c: drop support for
CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was
used in linking scripts to allow fine placement of embedded
environment sections.
This implies that GCC randomly places objects from env/embedded.o
and environment is not guaranteed to be located at the correct address:
04003df8 g F .text 00000038 mii_init
04004000 g O .text 00000004 env_size
04004004 g O .text 00002000 environment
04006004 g F .text 00000040 .hidden __lshrdi3
This patch restores this capability by allocating each object marked
with __UBOOT_ENV_SECTION__ into a different section. Hence
'environment' will be alone in .text.environment, allowing a
fine placement in u-boot.lds with:
. = DEFINED(env_offset) ? env_offset : .;
env/embedded.o (.text.environment)
Fixes 7653942b10e9e ("common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV")

is organised as follows:
- One 16kb block
- Two 8kb block
- One 32kb block
- Thirty one 64kb blocks
At the time being, u-boot is a single piece occupying the 320 first kbytes, then the environment is stored in the following 64kb block
The environment being quite tiny, we save one 64kb block by embedding
the environment in the first 8kb block.

Hi Tom,
If not applied already, please don't take this serie yet. While
migrating drivers to DM model, it find some caveats in the way mpc8xx is
initialised and it will be cleaner if I fix it in this serie rather than
making new patches on top of it.
