ec79d33b2c 85xx: Move to a common linker script
There are really no differences between all the 85xx linker scripts so
we can just move to a single common one.  Board code is still able to
override the common one if need be.

dfcd7f2160 Redundant Environment: protect full sector size
Several boards used different ways to specify the size of the
protected area when enabling flash write protection for the sectors
holding the environment variables: some used CONFIG_ENV_SIZE and
CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even
a mix of both for the "normal" and the "redundant" areas.

Normally, this makes no difference at all. However, things are
different when you have to deal with boards that can come with
different types of flash chips, which may have different sector
sizes.

Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the
biggest sector size, which may include several sectors on boards using
the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE
or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the
case that only the first of these sectors get protected, while the
following ones aren't.

This is no real problem, but it can be confusing for the user -
especially on boards that use CONFIG_ENV_SECT_SIZE to protect the
"normal" areas, while using CONFIG_ENV_SIZE_REDUND for the
"redundant" area.

To avoid such inconsistencies, I changed all sucn boards that I found
to consistently use CONFIG_ENV_SECT_SIZE for protection. This should
not cause any functional changes to the code.

f62fb99941 Fix all linker script to handle all rodata sections
A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script.  Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.

However, '*(.rodata*)' by itself will result in sub-optimal section
ordering.  The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file.  This is easy to fix by using the
SORT_BY_ALIGNMENT command.

This patch has not be tested one most of the boards modified.  Some boards
have a linker script that looks something like this:

*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)

I change this to:

*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))

This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

a5d212a263 mpc8xxx: LCRR[CLKDIV] is sometimes five bits
On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits
instead of four.

In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems.  It
should be safe as the fifth bit was defined as reserved and set to 0.

Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

dd332e18d0 85xx: socrates: fix DDR SDRAM tlb entry configuration
since commit be0bd8234b
tlb entry for socrates DDR SDRAM will be reconfigured
by setup_ddr_tlbs() from initdram() causing an
inconsistency with previously configured DDR SDRAM tlb
entry from tlb_table:

socrates>l2cam 7 9
IDX  PID      EPN  SIZE V TS           RPN U0-U3 WIMGE UUUSSS
  7 : 00 00000000 256MB V  0 -> 0_00000000  0000 -I-G- ---RWX
  8 : 00 00000000 256MB V  0 -> 0_00000000  0000 ----- ---RWX
  9 : 00 10000000 256MB V  0 -> 0_10000000  0000 ----- ---RWX

This patch makes the presence of the DDR SDRAM tlb entry in
the tlb_table dependent on CONFIG_SPD_EEPROM to avoid this
inconsistency.

9b827cf172 Align end of bss by 4 bytes

at a time. And the loop end is checked for an 'equal'
condition. Make the bss end address aligned by 4, so
that the loop will end as expected.

dfb49108e4 Pass dimm parameters to populate populate controller options
Because some dimm parameters like n_ranks needs to be used with the board
frequency to choose the board parameters like clk_adjust etc. in the
board_specific_paramesters table of the board ddr file, we need to pass
the dimm parameters to the board file.

* move ddr dimm parameters header file from /cpu to /include directory.
* add ddr dimm parameters to populate board specific options.
* Fix fsl_ddr_board_options() for all the 8xxx boards which call this function.

This patch adds Lime GDC support together with support for the PWM
backlight control through the w83782d chip.  The reset pin of the
latter is attached to GPIO, so we need to reset it in

- Set the LCRR_DBYP bit in the LCRR for local bus frequencies
  lower than 66 MHz and uses I/O accessor functions consequently.

- UPM data update.

- Update of default environment and configuration.  Use I2C multibus

9973e3c614 Change initdram() return type to phys_size_t
This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory.  phys_size_t is defined as an unsigned long on almost
all current platforms.

This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram).  It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.

Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.
