2011-02-21ARM: fix write*() I/O accessorsWolfgang Denk
Commit 3c0659b "ARM: Avoid compiler optimization for readb, writeb and friends." introduced I/O accessors with memory barriers. Unfortunately the new write*() accessors introduced a bug: The problem is that the argument "v" gets evaluated twice. This breaks code like used here (from "drivers/net/dnet.c"): for (i = 0; i < wrsz; i++) writel(*bufp++, &dnet->regs->TX_DATA_FIFO); Use auxiliary variables to avoid such problems.

2011-02-02arm926ejs: timer: Replace bss variable by gdrHeiko Schocher
Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss values in the arm926ejs timers implementation. The usage of bss values in drivers before initialisation of bss is forbidden.

2011-02-02ARM: Avoid compiler optimization for readb, writeb and friends.Alexander Holler
gcc 4.5.1 seems to ignore (at least some) volatile definitions, avoid that as done in the kernel. Reading C99 6.7.3 8 and the comment 114) there, I think it is a bug of that gcc version to ignore the volatile type qualifier used e.g. in __arch_getl(). Anyway, using a definition as in the kernel headers avoids such optimizations when gcc 4.5.1 is used. Maybe the headers as used in the current linux-kernel should be used, but to avoid large changes, I've just added a small change to the current headers.

2010-12-11davinci: Rewrite timer.c to use tbl/tbu emulation variables in gdNick Thompson
This change allows the davinci timer functions to be used before relocation since it avoids using static variables prior to BSS being made available. The code is based on that used in the at91 timers, modified to use a davinci specific hardware timer. It also maintains reset_timer() to allow deprecated timer usage to continue to work (for example, in nand_base.c) Signed-off-by: Nick Thompson <nick.thompson@ge.com> Tested-by: Ben Gardiner <bengardiner@nanometrics.ca> Tested-by: Sudhakar Rajashekhara <sudhakar.raj@ti.com> Tested-by: Sandeep Paulraj <s-paulraj@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

2010-12-09armv7: fix relocation skipAndreas Bießmann
I doubt the stack_setup() was defective before: we load the current location of _start and compare against destination of relocate_code().

2010-12-09arm: relocate_code(): do not set register uselessAndreas Bießmann

2010-12-09arm: copy_loop(): use scratch registerAndreas Bießmann

2010-11-30da850: Add RMII support for EMACSudhakar Rajashekhara
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.

2010-11-30Add board support for hawkboardSughosh Ganu
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).
