219f4788d3 hush.c: Move default CONFIG_SYS_PROMPT_HUSH_PS2 to hush.c
Exactly one board has defined CONFIG_SYS_PROMPT_HUSH_PS2 to a value
different than "> " which is vision2.  I have Cc'd the maintainer here
as I strongly suspect this is a bug rather than intentional behavior.

6b873dcabd Changes to move hawkboard to the new spl infrastructure
This patch moves hawkboard to the new spl infrastructure from the
older nand_spl one.

Removed the hawkboard_nand_config build option -- The spl code now
gets compiled with hawkboard_config, after building the main u-boot
image, using the CONFIG_SPL_TEXT_BASE. Modified the README.hawkboard
to reflect the same.

The V bit of the c1 register of CP15 should not be cleared on DA850

This patch reverts commit ca4b55800e

ae5c77dd90 da850evm: Move LPSC configuration to board_early_init_f()
Since commit f1d2b313c9 the serial
port of the da850evm is accessed before the UART2 peripheral of
the SoC is powered on in the function board_init() in
board/davinci/da8xxevm/da850evm.c.

When u-boot is used in conjunction with the UBL (user boot loader, see
doc/README.davinci) on this board, the UART2 peripheral is already
turned on by UBL at the time u-boot is started. Hence, the wrong
initialization sequence is not noticed by most users. However, if UBL is not
used, u-boot must power on the peripheral before using it.

This patch adds a board_early_init_f() function for the LPSC
configuration to the da850evm board configuration.

hence caches cant be used for da850 u-boot. As per new cache management
framework,if the caches are not used in u-boot, it needs to be explicitly

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.

4f6fc15b42 DA850 EVM: passing maximum clock rate information to kernel
The TI DA850/OMAP-L138/AM18x EVM can be populated with devices
having different maximum allowed CPU clock rating.

The maximum clock the chip can support can only be determined from
the label on the package (not software readable).

Introduce a method to pass the maximum allowed clock rate information
to kernel using ATAG_REVISION. The kernel uses this information to
determine the maximum cpu clock rate reachable using cpufreq.

Note that U-Boot itself does not set the CPU clock rate. The CPU
clock is setup by a primary bootloader ("UBL"). The rate setup by
UBL could be different from the maximum clock rate supported by the
device.

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.

at "Uncompressing Linux... done, booting the kernel."

'#define CONFIG_USE_NAND' at the top of the include/configs/da850evm.h file.

0f234d263b17ccf1b8fd776eb8c15b7cdb27a887 by Heiko Schocher <hs@denx.de>.

Without these changes gd->ram_size is '0' which leads to incorrect relocation
when CONFIG_SYS_ARM_WITHOUT_RELOC is defined and the board does not boot.

We use get_ram_size to dynamically calculate the available RAM because it runs
on different board version with different ram, as suggested by Heiko in private
communication.

Tested on a da850evm with 128M of DDR2 installed; with both
CONFIG_SYS_ARM_WITHOUT_RELOC defined and undefined.
