i.mx: introduce the armv7/imx-common folder

2011-12-09T16:30:10Z

In order to support the coming MX6 platform and to reducde the duplicated code, we had better move some common files or functions to the imx-common folder for sharing. This patch does the following: - move speed.c file from armv7/mx5/speed.c to armv7/imx-common/speed.c - move armv7/mx5/timer.c to armv7/imx-common/timer.c, no any new feature added but just fix the checkpatch errors in the old file and remove the CONFIG_SYS_MX5_CLK32 reference in the file - create one new file cpu.c file to store the common function with i.mx5/6 Signed-off-by: Jason Liu Cc:Stefano Babic Acked-by: Stefano Babic

mx5: Correct a warning in clock.c

2011-12-06T22:59:39Z

This corects the warning below, obtained with my gcc 4.6 compiler. arch/arm/cpu/armv7/mx5/libmx5.o: In function `decode_pll': arch/arm/cpu/armv7/mx5/clock.c:94: undefined reference to `__aeabi_uldivmod' I am not able to test this on MX5x hardware, but it does improve the MAKEALL output for me. You may already have a similar patch, but I cannot see it on the list. Signed-off-by: Simon Glass

mx53: Turn off child clocks before reconfigure perclk_root

2011-11-04T21:06:37Z

In addition to ensuring that PERCLK remains at least 2.5 times slower than the AHB clock, certain steps need to be followed to ensure robust operation of PERCLK when reconfiguring the PERCLK clock source. To properly configure the PERCLK clock source, the following steps are required: 1.In the CCGR registers, gate the clocks to all PERCLK-dependent modules. 2.Select the desired input clock for the PERCLK root clock (to be either source from the peripherals main source clock or the lp_apm clock source). Refer to the CMCBR register, perclk_lp_apm_sel bit. 3.Configure the perclk_pred1, perclk_pred2, and perclk_podf dividers to the desired setting. Refer to the CBCDR register for details. 4.In the CCGR registers, enable the desired clocks for the PERCLK-dependent module clocks. If these steps aren't followed, GPT timer may stop and the kernel stops at "Calibrating delay loop". Signed-off-by: Terry Lv Signed-off-by: Fabio Estevam

Makefile : fix generation of cpu related asm-offsets.h

2011-09-07T19:41:27Z

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. Signed-off-by: Stefano Babic CC: Matthias Weisser CC: Wolfgang Denk

MX: MX35 / MX5: uniform clock command with powerpc

2011-09-04T09:36:11Z

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
