* | ARM: zynq: add default ps7_init_gpl.c/h for Zed, MicroZed, ZC70xMasahiro Yamada2015-05-25-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to licensing issues, the files ps7_init.c/h are not able to be distributed with U-Boot source code. Recent Xilinx tools also provide the GPL variants (ps7_init_gpl.c/h), compatible with U-Boot license. Prior to this commit, we had to copy ps7_init files into board/xilinx/zynq/ before the compile. To be more user-friendly, let's include ps7_init_gpl.c/h for Zedboard, MicroZed, ZC702, ZC706. These init code have been taken from the hwplatform_templates directory of Xilinx SDK 2014.4. You can still use customized ps7_init_gpl.c/h by enabling CONFIG_ZYNQ_CUSTOM_INIT. The recommended directory for storing them is now board/xilinx/zynq/custom_hw_platform, but board/xilinx/zynq is still supported for backward compatibility. The latter emits a warning message to prompt users to gradually switch to the new directory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make DRAM_ODT_EN Kconfig setting a bool, add a separate DRAM_ODT_CORRECTION setting for A23 SoCs and use DRAM_ODT_EN Kconfig everywhere instead of only in dram_sun4i.c and hardcoding odt_en elsewhere. Note this commit makes no functional changes for existing boards, its purpose is to allow changing the odt_en value on future A33 boards. For sun4i/sun5i/sun7i boards which set DRAM_ODT_EN=y (which no defconfigs currently do) this patch turns on odt for both the DQ and the DQS lines, whereas previously it was possibly (but not desirable) to turn odt on only for one of them by setting the in DRAM_ODT_EN option to 1 or 2 instead of 3.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having bit 22 cleared in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. This was inspired by a patch from Catalin Marinas [1] and also from recent discussions in the linux-arm-kernel list [2] where Russell King and Rob Herring suggested that bootloaders should initialize the cache.

Introduce a new structure `struct mxc_i2c_bus`, this structure will used for non-DM and DM. 2. Remove `struct mxc_i2c_regs` structure, but use register offset to access registers based on `base` entry of `struct mxc_i2c_bus`. 3. Remove most `#ifdef I2C_QUIRK_REG`. Using driver_data to contain platform flags. A new flag is introduced, I2C_QUIRK_FLAG. 4. Most functions use `struct mxc_i2c_bus` as one of the parameters. Make most functions common to DM and non-DM, try to avoid duplicated code. 5. Support DM, but pinctrl is not included. Pinmux setting is still set by setup_i2c, but we do not need bus_i2c_init for DM. 6. struct i2c_parms and struct sram_data are removed. 7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist paramter of bus_i2c_init is modified to i2c index. Add new prototype i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for DM I2C and pinctrl is missed, we use a weak function for i2c_idle_bus. Board file take the responsibility to implement this function, like this: " int i2c_idle_bus(struct mxc_i2c_bus *i2c_bus) { if (i2c_bus->index == 0) force_bus_idle(i2c_pads_info0); else if (i2c_bus->index == 1) force_bus_idle(i2c_pads_info1); else xxxxxx } " 8. Introduce a weak function, enable_i2c_clk 9. Tested on an i.MX7 platform.

* | imx: mx27 move GPIO_PORTx to gpio.hPeng Fan2015-05-14-22/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | These GPIO_PORTx macros should be in gpio.h, but not in imx-regs.h. Also, imx-regs.h and iomux-v3.h has same macro defintion for GPIO_PORTx, and both of them are included in mxc_i2c.c(include mxc_i2c.h). This will incur build warnings with macro redefinition. Since iomux-v3.h is not compatible with mx27, we can not simply include iomux-v3.h for mx27, so move the GPIO_PORTx to gpio.h to fix the build warning.

| | | | | | | | | | | | | | | | It is convenient for some boards to implement save_boot_params() in C rather than assembler. Provide a way to return in this case. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
