* davinci: Rewrite timer.c to use tbl/tbu emulation variables in gdNick Thompson2010-12-11-49/+28
| | | | | | | | | | | | | | | | | 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>

* | arm: fixloop(): do not use r8 for relocationAndreas Bießmann2010-12-09-3/+3
| | | | | | | | | | | | | | | | | | r8 is used for global_data and should therefore be left alone! For C code the compiler flag --fixed-r8 does the job, but in assembler we need to be aware of that fact. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
* | arm: relocate_code(): do not set register uselessAndreas Bießmann2010-12-09-2/+2
| | | | | | | | | | | | | | | | | | In case we are still at relocation target address before relocation we do not need to load the registers needed for relocation. We should instead skip the whole relocation part and jump over to clear_bss immediately. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
* | arm: copy_loop(): use scratch registerAndreas Bießmann2010-12-09-5/+5
| | | | | | | | | | | | | | | | | | This patch uses r1 as scratch register for copy_loop(). Therefore we do not longer need r7 for the storage of relocate_code()'s 'addr_moni' (the destination address of relocation). Therefore r7 can be used later on for other purposes.

* | Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* | ARM: fix linker file for newer ld supportAlbert Aribaud2010-11-17-12/+18

| * Kirkwood: bugfix: DRAM size initializationTanmay Upadhyay2010-10-28-0/+10
| | | | | | | | | | | | | | | | | | If start of any DRAM bank is greater than total DDR size, remaining DDR banks' start address & size were left un-initialized in dram_init function. This could break other functions who uses array 'gd->bd->bi_dram'. Kirkwood network driver is one example. This also stops Linux kernel from booting. v2 - Set start address also to 0. Without this Linux kernel couldn't boot up Signed-off-by: Tanmay Upadhyay <tanmay.upadhyay@einfochips.com>

* | | Drop support for CONFIG_SKIP_RELOCATE_UBOOTWolfgang Denk2010-10-29-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For ARM systems, before ELF relocation was introduced, CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the U-Boot image from whereever it was loaded to it's link address (CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation was performed at all, it was just a memcpy(). With ELF relocation, this does not work like that any more, and related boards need to be fixed anyway. So don't keep this relict any longer. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>
* | | Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk2010-10-29-111/+0
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>

* | Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* at91: Add arch_preboot_os which disables PIT in a faster wayAlexander Stein2010-10-05-0/+16
| | | | | | | | | | | | When disabled the PIT runs until it reaches the CPIV value. The Linux PIT driver stops the PIT and waits until it stopped. This can take over 100ms. Simply stopping in u-boot isn't sufficient as the PIT will still be running when Linux is waiting until it stopped. So, we stop it in u-boot by setting the compare value to a value slightly greater than the current running counter to make the PIT stopped in short time.
