8 years agosunxi: Reserve ATF memory space on A64

today resides in the first 16MB of RAM. So we should make sure we reserve

not found), reset is asserted to stop execution. If the RESET_REQ
is not tied to HRESET, this allows the execution to continue.

crypto/fsl: Make CAAM transactions cacheable

This commit solves CAAM coherency issue on ls2080. When caches are
enabled and CAAM's DMA's AXI transcations are not made cacheable,
Core reads/writes data from/to caches and CAAM does from main memory.
This forces data flushes to synchronize various data structures. But
even if any data in proximity of these structures is read by core,
these structures again are fetched in caches.

To avoid this problem, either all the data that CAAM accesses can be
made cache line aligned or CAAM transcations can be made cacheable.

So, this commit makes CAAM transcations as write back with write and
read allocate.

    Implement bus recovery methods for i2c-imx so we can recover from
    situations where SCL/SDA are stuck low.

    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 = <
