a429db7e3c arm920t/at91/timer: replace bss variables by gd
Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc
bss values in arm920t/at91/timer driver.
The usage of bss values in driver before initialisation of bss is
forbidden. In that special case some data in .rel.dyn gets corrupted by
the arm920t/at91/timer driver.

d26074012b da850: Add RMII support for EMAC
This patch is a port of the work by Sudhakar Rajeshekhara in commit
ab3effbcad8851cc65dc5241a01c064d2030a3b2 of
git://arago-project.org/git/people/sandeep/u-boot-davinci.git.

The da850 UI board has on it an RMII PHY which can be used if the MDC line
to the MII PHY on the baseboard is disabled and the RMII PHY is enabled by
configuring the values of some GPIO pins on the IO expander of the UI board.
This patch implements disabling that line via GPIO2[6], configuring the UI
board's IO expander and setting only the pinmux settings that are needed for
RMII operation.

Tested on da850evm by adding a define for CONFIG_DRIVER_TI_EMAC_USE_RMII.

48571ff005 Add board support for hawkboard
The patch adds basic board support for TI's OMAP-L138 based
Hawkboard. This board is pretty similar to the da850 EVM. Support for
nand and network access is added in this version.

The following bootup procedure is used.

At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand
controllers and copies the second stage bootloader(nand_spl) to
RAM. The secondary bootloader then copies u-boot from a predefined
location in the nand flash to the RAM, and passes control to the
u-boot image.

Three config options are supported
* hawkboard_config - Used to create the u-boot.bin. Tftp the
 u-boot.bin image to the RAM from u-boot, and flash to the nand flash
 at address 0xe0000.

* hawkboard_nand_config - Used to generate the secondary
 bootloader(nand_spl) image. This creates an elf file u-boot-spl
 under nand_spl/. Create an AIS signed image using this file, and
 flash it to the nand flash at address 0x20000. The ais file should
 fit in one block.

* hawkboard_uart_config - This is same as the first image, but with
 the TEXT_BASE as expected by the RBL(0xc1080000). Create the AIS

a9aa392629 Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC
When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support.  However, other recent changes led to a different
implementation (ELF relocation), where this no longer works.  By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.

So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

  0x1FFE8000 which is for older revision.

- Include imx-regs.h in mx51evk.h

  Definitions like CSD0_BASE_ADDR and IRAM_BASE_ADDR can be
  referred to.

- Define CONFIG_SYS_INIT_RAM_ADDR and CONFIG_SYS_INIT_RAM_SIZE

  They are used to define init RAM layout.

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.

7b37a27e14 davinci_emac: davinci_eth_set_mac_addr to ->write_hwaddr
This patch proposes to migrate the davinci_emac driver to using the
eth_device->write_hwaddr function pointer as suggested by Ben Warren.

All the davinci boards had the behaviour, prior to this patch, of
sync'ing the environment variable enetaddr with the MAC address read
from non-volatile storage on boot -- when the two locations disagreed,
the environment variable value took precendence. This patch keeps the
same behaviour but lets eth_initialize take care of it.

This patch refactors davinci_emac setup in the boards so that the MAC
address is read from non-volatile storage into the environment variable
and then the environment variable value is use in eth_intialize. The
only exception is the direct call to davinci_eth_set_mac_addr made by
the da830evm board init which was changed into an assignment of the
enetaddr field.

ea882baf9c New implementation for internal handling of environment variables.
Motivation:

* Old environment code used a pessimizing implementation:
  - variable lookup used linear search => slow
  - changed/added variables were added at the end, i. e. most
    frequently used variables had the slowest access times => slow
  - each setenv() would calculate the CRC32 checksum over the whole
    environment block => slow
* "redundant" envrionment was locked down to two copies
* No easy way to implement features like "reset to factory defaults",
  or to select one out of several pre-defined (previously saved) sets
  of environment settings ("profiles")
* No easy way to import or export environment settings

======================================================================

API Changes:

- Variable names starting with '#' are no longer allowed

  I didn't find any such variable names being used; it is highly
  recommended to follow standard conventions and start variable names
  with an alphanumeric character

- "printenv" will now print a backslash at the end of all but the last
  lines of a multi-line variable value.

  Multi-line variables have never been formally defined, allthough
  there is no reason not to use them. Now we define rules how to deal
  with them, allowing for import and export.

- Function forceenv() and the related code in saveenv() was removed.
  At the moment this is causing build problems for the only user of
  this code (schmoogie - which has no entry in MAINTAINERS); may be
  fixed later by implementing the "env set -f" feature.

Inconsistencies:

- "printenv" will '\\'-escape the '\n' in multi-line variables, while
  "printenv var" will not do that.

======================================================================

Advantages:

- "printenv" output much better readable (sorted)
- faster!
- extendable (additional variable properties can be added)
- new, powerful features like "factory reset" or easy switching
  between several different environment settings ("profiles")

Disadvantages:

- Image size grows by typically 5...7 KiB (might shrink a bit again on
  systems with redundant environment with a following patch series)

======================================================================

Implemented:

- env command with subcommands:

  - env print [arg ...]

    same as "printenv": print environment

  - env set [-f] name [arg ...]

    same as "setenv": set (and delete) environment variables

    ["-f" - force setting even for read-only variables - not
    implemented yet.]

  - end delete [-f] name

    not implemented yet

    ["-f" - force delete even for read-only variables]

  - env save

    same as "saveenv": save environment

  - env export [-t | -b | -c] addr [size]

    export internal representation (hash table) in formats usable for
    persistent storage or processing:

	-t:	export as text format; if size is given, data will be
		padded with '\0' bytes; if not, one terminating '\0'
		will be added (which is included in the "filesize"
		setting so you can for exmple copy this to flash and
		keep the termination).
	-b:	export as binary format (name=value pairs separated by
		'\0', list end marked by double "\0\0")
	-c:	export as checksum protected environment format as
		used for example by "saveenv" command
	addr:	memory address where environment gets stored
	size:	size of output buffer

	With "-c" and size is NOT given, then the export command will
	format the data as currently used for the persistent storage,
	i. e. it will use CONFIG_ENV_SECT_SIZE as output block size and
	prepend a valid CRC32 checksum and, in case of resundant
	environment, a "current" redundancy flag. If size is given, this
	value will be used instead of CONFIG_ENV_SECT_SIZE; again, CRC32
	checksum and redundancy flag will be inserted.

	With "-b" and "-t", always only the real data (including a
	terminating '\0' byte) will be written; here the optional size
	argument will be used to make sure not to overflow the user
	provided buffer; the command will abort if the size is not
	sufficient. Any remainign space will be '\0' padded.

        On successful return, the variable "filesize" will be set.
        Note that filesize includes the trailing/terminating '\0'
        byte(s).

        Usage szenario: create a text snapshot/backup of the current
	settings:

		=> env export -t 100000
		=> era ${backup_addr} +${filesize}
		=> cp.b 100000 ${backup_addr} ${filesize}

	Re-import this snapshot, deleting all other settings:

		=> env import -d -t ${backup_addr}

  - env import [-d] [-t | -b | -c] addr [size]

    import external format (text or binary) into hash table,
    optionally deleting existing values:

	-d:	delete existing environment before importing;
		otherwise overwrite / append to existion definitions
	-t:	assume text format; either "size" must be given or the
		text data must be '\0' terminated
	-b:	assume binary format ('\0' separated, "\0\0" terminated)
	-c:	assume checksum protected environment format
	addr:	memory address to read from
	size:	length of input data; if missing, proper '\0'
		termination is mandatory

  - env default -f

    reset default environment: drop all environment settings and load
    default environment

  - env ask name [message] [size]

    same as "askenv": ask for environment variable

  - env edit name

    same as "editenv": edit environment variable

  - env run

    same as "run": run commands in an environment variable

======================================================================

TODO:

- drop default env as implemented now; provide a text file based
  initialization instead (eventually using several text files to
  incrementally build it from common blocks) and a tool to convert it
  into a binary blob / object file.

- It would be nice if we could add wildcard support for environment
  variables; this is needed for variable name auto-completion,
  but it would also be nice to be able to say "printenv ip*" or
  "printenv *addr*"

- Some boards don't link any more due to the grown code size:
  DU405, canyonlands, sequoia, socrates.

91a76751a0 Make getenv() work before relocation.
So far, getenv() would work before relocation is most cases, even
though it was not intended to be used that way.  When switching to a
hash table based implementation, this would break a number of boards.

For convenience, we make getenv() check if it's running before
relocation and, if so, use getenv_f() internally.

Note that this is limited to simple cases, as we use a small static
buffer (32 bytes) in the global data for this purpose.

For this reason, it is also not a good idea to convert all current
uses of getenv_f() into getenv() - some of the existing use cases need
to be able to deal with longer variable values, so getenv_f() is still
needed and recommended for use before relocation.
