Fix build issues cause by LDFLAGS_FINAL changes

2011-03-31T21:38:16+00:00

Commit 6dc1ece "Introduce a new linker flag LDFLAGS_FINAL" modified a
number of Makefiles in a way that broke out-of-tree builds.  The
problem was that $(nandobj) was used before it got defined.

Fix this.

SMDK6400: Add some labels to u-boot.lds to support nand_spl

2011-03-27T17:19:16+00:00

In the nand_spl feature of SMDK6400. Add some relocation symbols to
nand_spl/board/samsung/smdk6400/u-boot.lds to fix the compile error.

rename _end to __bss_end__

2011-03-27T17:18:37+00:00

Currently, _end is used for end of BSS section.  We want _end to mean
end of u-boot image, so we rename _end to __bss_end__ first.

Introduce a new linker flag LDFLAGS_FINAL

2011-03-22T22:32:06+00:00

commit 8aba9dceebb14144e07d19593111ee3a999c37fc
Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS

breaks the usage of --gc-section to build nand_spl. We still need linker option
--gc-section for every uboot image, not only the main one. LDFLAGS_FINAL passes
the --gc-sections to each uboot image.

To get the proper linker flags, we use LDFLAGS and LDFLAGS_FINAL to replace
PLATFORM_LDFLAGS in the Makefile of each nand_spl board.

PowerPC, nand_spl: Add relocation support for -fpic

2010-12-17T19:25:19+00:00

By rearranging the linker script we get support for
relocation of -fpic for free.
Move __got2_entries outside _GOT2_TABLE_ defining scope
matching the rest of PowerPC

powerpc/nand spl: link libgcc

2010-12-16T22:19:14+00:00

Recent GCC (4.4+) performs out-of-line epilogues in some cases, when
optimizing for size.  It causes a link error for _restgpr_30_x (and similar)
if libgcc is not linked.

It actually increases size with very small binaries, due to the fixed size
of the out-of-line code, and not having any functions that actually need to
restore more than 2 or 3 registers.  But I don't see a way to turn it off,
other than asking GCC to optimize for speed -- which may also increase
size for some boards.

Davinci 8xx: Move common functions to share code

2010-11-30T16:32:59+00:00

As more Davinci 8xx board can be added, move common code
to be shared between boards.

 * rebased ontop of Sugosh's patches
 * moving the HAWKBOARD_KICK{0,1}_UNLOCK defines to
   arch/arm/include/asm/arch-davinci/davinci_misc.h from to
   arch/arm/include/asm/arch-davinci/da8xx_common.h
 * don't define dram functions in PRELOADER
 * move sync_env_enetaddr into existing EMAC ifdef
 * use misc.c in hawkboard nand_spl

Add board support for hawkboard

2010-11-30T16:25:01+00:00

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
