* MX5: Modify the PLL decoding algorithmMarek Vasut2011-09-30-10/+56
| | | | | | | | | | The PLL decoding algorithm didn't take into account many configuration bits. Adjust it according to Linux kernel. Also, add PLL4 for MX53.

* Makefile : fix generation of cpu related asm-offsets.hStefano Babic2011-09-07-3/+1
| | | | | | | | | | | commit 0edf8b5b2fa0d210ebc4d6da0fd1aceeb7e44e47 breaks building on a different directory with the O= parameter. The patch wil fix this issue, generating always asm-offsets.h before the other targets.

* MX: MX35 / MX5: uniform clock command with powerpcStefano Babic2011-09-04-2/+2
| | | | | | | | | | | There was already a command to show the processor clocks for PowerPC (clocks). For i.MX, the "clockinfo" command was introduce. The patch sets the same command name used on PowerPC. A nasty and not needed newline is also dropped in the help for the command. Signed-off-by: Stefano Babic <sbabic@denx.de>
* ARM: MX51: PLL errata workaroundDavid Jander2011-09-04-0/+38
| | | | | | | | | | | | | This is a port of the official PLL errata workaround from Freescale to mainline u-boot. The PLL's in the i.MX51 processor can go out of lock due to a metastable condition in an analog flip-flop when used at high frequencies. This workaround implements an undocumented feature in the PLL (dither mode), which causes the effect of this failure to be much lower (in terms of frequency deviation), avoiding system failure, or at least decreasing the likelihood of system failure.

* Timer: Remove reset_timer_masked()Graeme Russ2011-07-26-6/+4
| | | | | | | In some circumstances, reset_timer_masked() was called be timer_init() in order to perform architecture specific timer initialisation. In such cases, the required code in reset_timer_masked() has been moved into timer_init()

* ARM: MX5: Fix broken leftover TO-2 errata workaroundDavid Jander2011-07-18-1/+5
| | | | | | | | This check was broken. r3 does not contain the silicon revision anymore, so we need to reload it. Also, this errata only applies to i.MX51. Signed-off-by: David Jander <david@protonic.nl> Acked-by: Stefano Babic <sbabic@denx.de>

* MX5: Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bssStefano Babic2011-02-02-2/+4
| | | | | | | | | | The usage of bss values in drivers before initialisation of bss is forbidden. In that special case some data in .rel.dyn gets corrupted. This patch is the same as recently applied for arm926js architecture. Signed-off-by: Stefano Babic <sbabic@denx.de> CC: Heiko Schocher <hs@denx.de>

* | Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
