* i.mx: introduce the armv7/imx-common folderJason Liu2011-12-09-86/+173
| | | | | | | | | | | | | | | | | 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 <jason.hui@linaro.org> Cc:Stefano Babic <sbabic@denx.de> Acked-by: Stefano Babic <sbabic@denx.de>
* S5PC2XX: Rename S5pc2XX to exynosChander Kashyap2011-12-09-152/+152
| | | | | | | | | | | | | | 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 upSimon Glass2011-12-09-9/+1
| | | | | | | | | | 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.

* tegra2: Enable instruction cacheSimon Glass2011-12-09-0/+3

* arm: Move CP15 init out of cpu_init_crit()Simon Glass2011-12-09-6/+21
| | | | | | | | | | | | | | | | | | | | 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.

* tegra2: Simplify tegra_start() boot pathSimon Glass2011-12-09-25/+37
| | | | | | | | | | | | | | | | | 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 <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra2: Add arch_cpu_init() to fire up Cortex-A9Simon Glass2011-12-09-4/+22
| | | | | | | | | | | | | We want to move away from a special Tegra2 start-up, and just use arch_cpu_init() instead. However, if we run board_init_f() from boot we need to build it for ARMv4T, since the Tegra's AVP start-up CPU does not support ARMv7. The effect of this is to do the AVP init earlier, and in arch_cpu_init(), rather that board_early_init_f().

* tegra2: Use new GPIO APIs in gpio_config_uart()Stephen Warren2011-12-09-18/+6
| | | | | | | | | | | | | | | ... rather than open-coding the register accesses. However, gpio_request() typically stores the "label" parameter in a global data structure. This causes problems when called from gpio_config_uart(), since the code is running before relocation. To solve this, pass a NULL string to gpio_request(), and modify gpio_request() not to touch the string if it's NULL.

| | | | | | | | | | | | | | Ventana is a board which is very similar to Seaboard. Support it by re-using board/nvidia/seaboard/seaboard.c with minor run-time conditionals. v5: Makefile: Use cmd_link_o_target, remove unused clean/distclean targets. v6: Make gpio_config_uart_seaboard() static. v7: Add MAINTAINERS entry for Ventana.

* tegra2: Modify MMC driver to handle power and cd GPIOsStephen Warren2011-12-09-64/+45
| | | | | | | | | | | | | | | | | | | | | | | Pass the GPIO numbers for power and card detect to tegra2_mmc_init(), and modify that function to perform all required GPIO initialization. This removes the need for board files to perform these operations. Move board_mmc_getcd() into tegra2_mmc.c now that the driver knows which GPIOs to use. Update affected call-sites in seaboard.c and harmony.c. Note that this change should make all SD ports work on Harmony, since the required GPIO setup is now being performed. v4: Fix prototype of tegra2_mmc_init() in board.h to match driver change.

* tegra2: Move board_mmc_init into board filesStephen Warren2011-12-09-52/+109
| | | | | | | | | | | | | | | | | | | | For Seaboard, this is mostly a cut/paste of board_mmc_init() and pin_mux_mmc() into seaboard.c; pin_mux_mmc() was modified to add some missing pinmux_tristate_disable calls for the GPIOs. For Harmony, those functions were modified to configure SDMMC2 (index 2) instead of SDMMC3 (index 1), since that's what is present on the board. However, harmony.c is still missing the required GPIO setup, so neither port is likely to function correctly yet. This will be fixed in the next change. v4: Include board.h to prototype tegra2_mmc_init().

* ne2000: Convert to new net-multi model, fixes build of three boardsBernhard Kaindl2011-12-08-29/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the build of the two sh boards shmin and r7780mp and qemu-mips which currently fail to build due to dropped pre-CONFIG_NET_MULTI code. This v2 patch minimizes the number of lines in the diff for easy review and to eliminate any possible accidential changes resulting from moving lines of code in the file. This also makes the register function very easy. Any cleanups and improvements are intentionally deferred to follow-up patches to keep this patch as simple and as easy to review as possible. A new driver register function, ne2k_register() calls the existing one-time setup part of the old init function and calls eth_register(). Changes to shmin, r7780mp and qemu-mips: - Call the new ne2k_register() from board_eth_init() of the boards. - Tested using qemu-mips board, - Tested the two renesas / sh boards r7780mp and shmin to compile again, and should work. checkpatch-clean when "--ignore VOLATILE" is added to .checkpatch.conf, and no warnings introduced in none of the three boards using this driver.

* | powerpc: Minimal private libgcc to build on DebianKyle Moffett2011-12-07-1/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Standard Debian powerpc and powerpcspe systems only include hard-float libgcc in their native compilers, which causes scary build warnings when building U-Boot. Debian and other PowerPC-supporting distributions used to provide libgcc and other libraries in a "nof" (soft-float) form in the "multilib" packages. As they were completely unused by the distribution and therefore tended to be very buggy it was decided to save some time on the part of the maintainers and build-servers by removing them. Admittedly, right now the linker warnings do not indicate any problems, as the included routines do not use any floating point at all. The concern is that if floating-point code were ever added it might cause hard-float code to be unexpectedly included in U-Boot without generating a hard error. This would cause unexplained crashes or indeterminate results at runtime. The easiest way to resolve this is to borrow the routines that U-Boot needs from the Linux kernel, which has the same issue. Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3().
