* arm: clang: Update support slightlyTom Rini2016-04-01-1/+8
| | | | | | | | | | | - Move most of the flags required into LLVM_RELFLAGS to test at build time instead of requiring them to be passed in. - Update doc/README.clang to reflect this - Switch to rpi_2 as the example as it's closer to working out of the box than rpi is.

| * sunxi: Add Pine64+ supportSiarhei Siamashka2016-04-01-0/+203
| | | | | | | | | | | | | | | | | | | | | | | | | | The Pine64+ is a system based on the Allwinner A64 SoC. It is capable of running AArch64 code and thus is the first of its kind for the sunxi target. This patch adds a defconfig and device tree chunks for it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Allwinner A64 SoC is used in the Pine64. This patch adds all bits necessary to compile U-Boot for it running in AArch64 mode. Unfortunately SPL is not ready yet due to legal problems, so we need to boot using the binary boot0 for now.

| * sunxi: Explicitly cast u32 pointer conversionsAlexander Graf2016-04-01-4/+4
| | | | | | | | | | | | | | | | | | | | | | Some parts of the sunxi code cast explicitly between u32 values and pointers. This is not a problem in practice, because all 64bit SoCs today only use the lower 32 bits for their phyical address space. But we need to make sure that the compiler is sure this is not an accident as well.

When secure boot is enabled, default bootcmd is changed to first validate bootscript using the header and then execute the script. For ls2080, NOR memory map is different from other ARM SoCs. So a new address on NOR is used for this bootscript header (0x583920000). The Bootscript address is mentioned in this header along with addresses of other images.

Once i2c bus SCL/SDA are stuck low during transfer, config the i2c pinctrl to gpio mode by calling pinctrl sleep set function, and then use GPIO to emulate the i2c protocol to send nine dummy clock to recover i2c device. After recovery, set i2c pinctrl to default group setting. " See Documentation/devicetree/bindings/i2c/i2c-imx.txt for detailed description. 1. Introuduce scl_gpio/sda_gpio/bus in mxc_i2c_bus. 2. Discard the __weak attribute for i2c_idle_bus and implement it, since we have pinctrl driver/driver model gpio driver. We can use device tree, but not let board code to do this. 3. gpio state for mxc_i2c is not a must, but it is recommended. If there is no gpio state, driver will give tips, but not fail. 4. The i2c controller was first probed, default pinctrl state will be used, so when need to use gpio function, need to do "pinctrl_select_state(dev, "gpio")" and after force bus idle, need to switch back "pinctrl_select_state(dev, "default")". This is example about how to use the gpio force bus idle function: " &i2c1 { clock-frequency = <100000>; pinctrl-names = "default", "gpio"; pinctrl-0 = <&pinctrl_i2c1>; pinctrl-1 = <&pinctrl_i2c1_gpio>; scl-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>; sda-gpios = <&gpio1 29 GPIO_ACTIVE_HIGH>; status = "okay"; [....] }; [.....] pinctrl_i2c1_gpio: i2c1grp_gpio { fsl,pins = < MX6UL_PAD_UART4_TX_DATA__GPIO1_IO28 0x1b8b0 MX6UL_PAD_UART4_RX_DATA__GPIO1_IO29 0x1b8b0 >; }; " Signed-off-by: Peng Fan <van.freenix@gmail.com> Cc: Albert Aribaud <albert.u.boot@aribaud.net> Cc: Stefano Babic <sbabic@denx.de> Cc: Heiko Schocher <hs@denx.de> Cc: Simon Glass <sjg@chromium.org> Cc: York Sun <york.sun@nxp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dma_addr_t holds any valid DMA address. If the DMA API only uses 32-bit addresses, dma_addr_t need only be 32 bits wide. Bus addresses, e.g., PCI BARs, may be wider than 32 bits, but drivers do memory-mapped I/O to ioremapped kernel virtual addresses, so they don't care about the size of the actual bus addresses. Also 32 bit ARM systems with LPAE enabled can use 64bit address space, but DMA still use 32bit address like in case of DRA7 and Keystone platforms.

Some boards however (like the RPi2) run in HYP mode. There, we need to modify the HYP version of system registers and HYP mode only supports the long descriptor PTE format. So this patch introduces support for both long descriptor PTEs and HYP mode registers. Signed-off-by: Alexander Graf <agraf@suse.de>
* | arm64: Add 32bit arm compatible dcache definitionsAlexander Graf2016-03-27-1/+5
| | | | | | | | | | | | | | | | | | | | | | We want to be able to reuse device drivers from 32bit code, so let's add definitions for all the dcache options that 32bit code has. While at it, fix up the DCACHE_OFF configuration. That was setting the bits to declare a PTE a PTE and left the MAIR index bit at 0. Drop the useless bits and make the index explicit.
