| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we need to build one U-boot image for each of the wandboard variants: quad, dual-lite and solo.

* | ARM: zynq: add default ps7_init_gpl.c/h for Zed, MicroZed, ZC70xMasahiro Yamada2015-05-252-1/+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.

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.

* | mx6: Set shared override bit in PL310 AUX_CTRL registerFabio Estevam2015-05-152-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Currently the code uses impossible values for mem_speed (1333, 1600 MT/s) for calculating the DDR timings, and uses fixed clock (528 or 400 MHz) which doesn't take into account DDR3 memory limitations.

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.

| * | ARM: tegra: move NVIDIA common files to arch/arm/mach-tegraMasahiro Yamada2015-05-134-1/+326
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the Tegra boards borrow the files from board/nvidia/common/ directory, i.e., board/nvidia/common/* are not vendor-common files, but SoC-common files. Move NVIDIA common files to arch/arm/mach-tegra/ to clean up Makefiles. As arch/arm/mach-tegra/board.c already exists, this commit renames board/nvidia/common/board.c to arch/arm/mach-tegra/board2.c, expecting they will be consolidated as a second step.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The secure world code is relocated to the MB just below the top of 4G, we reserve it in the FDT (by setting CONFIG_ARMV7_SECURE_RESERVE_SIZE) but it is not protected in h/w.

| * | tegra: Boot in non-secure mode by defaultJan Kiszka2015-05-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream Linux is broken with default configs when PSCI, thus non-secure mode is enabled. So the user should explicitly enable this mode, e.g. when she disabled CONFIG_CPU_IDLE in Linux (in which case it's safe to use). We can revert this workaround once Linux got fixed.

| * | ARM: tegra: Enable SMMU when going non-secureThierry Reding2015-05-132-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sure to enable the SMMU when booting the kernel in non-secure mode. This is necessary because some of the SMMU registers are restricted to TrustZone-secured requestors, hence the kernel wouldn't be able to turn the SMMU on. At the same time, enable translation for all memory clients for the same reasons. The kernel will still be able to control SMMU IOVA translation using the per-SWGROUP enable bits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We only set CNTFRQ in arch_timer_init for the boot CPU. But this has to happen for all cores. Fixing this resolves problems of KVM with emulating the generic timer/counter.

| * | tegra124: Reserve secure RAM using MC_SECURITY_CFG{0, 1}_0Ian Campbell2015-05-133-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These registers can be used to prevent non-secure world from accessing a megabyte aligned region of RAM, use them to protect the u-boot secure monitor code. At first I tried to do this from s_init(), however this inexplicably causes u-boot's networking (e.g. DHCP) to fail, while networking under Linux was fine. So instead I have added a new weak arch function protect_secure_section() called from relocate_secure_section() and reserved the region there. This is better overall since it defers the reservation until after the sec vs. non-sec decision (which can be influenced by an envvar) has been made when booting the os.

| * | tegra124: Add PSCI support for Tegra124Jan Kiszka2015-05-135-0/+174
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is based on Thierry Reding's work and uses Ian Campell's preparatory patches. It comes with full support for CPU_ON/OFF PSCI services. The algorithm used in this version for turning CPUs on and off was proposed by Peter De Schrijver and Thierry Reding in http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/210881. It consists of first enabling CPU1..3 via the PMC, just to powergate them again with the help of the Flow Controller. Once the Flow Controller is in place, we can leave the PMC alone while processing CPU_ON and CPU_OFF PSCI requests.

| * | virt-dt: Allow reservation of secure region when in a RAM carveoutJan Kiszka2015-05-133-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In this case the secure code lives in RAM, and hence the memory node in the device tree needs to be adjusted. This avoids that the OS will map and possibly access the reservation. Add support for setting CONFIG_ARMV7_SECURE_RESERVE_SIZE to carve out such a region. We only support cutting off memory from the beginning or the end of a RAM bank as we do not want to increase their number (which would happen if punching a hole) for simplicity reasons This will be used in a subsequent patch for Jetson-TK1.
