arm: Tegra: fix undefined instruction hang immediately after reset

2011-12-21T19:36:22Z

commit 0d479b53 (Aneesh V) added code for OMAP4 that doesn't execute on Tegra, due to the AVP (ARM7TDI) not having a CP15. Result was an undefined instruction hang just after reset. Signed-off-by: Tom Warren Cc: Albert Aribaud Cc: Tom Rini Acked-by: Aneesh V

i.mx: add the initial support for freescale i.MX6Q processor

2011-12-09T16:30:10Z

i.MX6Q is freescale quad core processors with ARM cortex_a9 complex. This patch is to add the initial support for this processor. Signed-off-by: Jason Liu Cc:Stefano Babic

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

S5PC2XX: Rename S5pc2XX to exynos

2011-12-09T16:30:09Z

As per new naming convention for Samsung SoC's, all Cortex-A9 and Cortex-A15 based SoC's will be classified under the name Exynos. Cortex-A9 and Cortex-A15 based SoC's will be sub-classified as Exynos4 and Exynos5 respectively. In order to better adapt and reuse code across various upcoming Samsung Exynos based boards, all uses of s5pc210 prefix/suffix/directory-names are renamed in this patch. s5pc210 is renamed as exynos4210 and S5PC210/s5pc210 suffix/prefix are renamed as exynos4/EXYNOS4.

tegra2: Don't use board pointer before it is set up

2011-12-09T16:30:09Z

In board_init_f() the gd->bd pointer is not valid when dram_init() is called. This only avoids dying because DRAM is at zero on Tegra2. The common ARM routine sets up the banks in the same way anyway, so we can just remove this code. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra2: Remove unneeded 'dynamic ram size' message

2011-12-09T16:30:09Z

This message is not required, since it is followed by an 'official' U-Boot message. U-Boot 2011.03-00048-gd7cb0d3 (May 11 2011 - 17:17:23) TEGRA2 Board: NVIDIA Seaboard dynamic ram_size = 1073741824 DRAM: 1 GiB becomes: TEGRA2 Board: NVIDIA Seaboard DRAM: 1 GiB This is a separate commit since it changes behavior.

tegra2: Remove unneeded boot code

2011-12-09T16:30:09Z

Since we have cache support built in we can remove Tegra's existing cache initialization code amd other related dead code. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

arm: Move CP15 init out of cpu_init_crit()

2011-12-09T16:30:09Z

Some SOCs have do not start up with their 'main' CPU. The first U-Boot code may then be executed with a CPU which does not have a CP15, or not a useful one. Here we split the initialization of CP15 into a separate call, which can be performed later if required. Once the main CPU is running, you should call cpu_init_cp15() to perform this init as early as possible. Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not need to change, this CP15 init is still skipped in that case. The only impact for these boards is that the cpu_init_cp15() will be available even if it is never used on these boards. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra2: Simplify tegra_start() boot path

2011-12-09T16:30:09Z

The Tegra2 boot path is more complicated than it needs to be. Since we want to move to building most of U-Boot with ARMv7 and only a small part with ARMv4T (for AVP) it should be as simple as possible. This makes tegra2_start() into a simple function which either does AVP init or A9 init depending on which core is running it. Both cores now following the same init path, beginning at _start, and the special Tegra2 boot path code is no longer required. Only two files need to be built for ARMv4T, and this is handled in the Tegra2 CPU Makefile. Signed-off-by: Simon Glass Signed-off-by: Tom Warren
