4491327d59 Remove arch/${ARCH}/include/asm/errno.h
Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of <asm-generic/errno.h>.  Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.

Now all of include directives for <asm/errno.h> are gone.
Deprecate <asm/errno.h>.

b63f8a4336 arm: fsl: Adjust ordering of #ifndef CONFIG_SPL_BUILD
The secure boot header files incorrectly define SPL options only if
CONFIG_SPL_BUILD is defined. This means that the options are only enabled
in an SPL build, and not with a normal 'make xxx_defconfig'. This means
that moveconfig.py cannot work, since it sees the options as disabled even
when they may be manually enabled in an SPL build.

Fix this by changing the order.

71fe22256c fsl: serdes: ensure accessing the initialized maps of serdes protocol
Up to now, the function is_serdes_configed() doesn't check if the map
of serdes protocol is initialized before accessing it. The function
is_serdes_configed() will get wrong result when it was called before
the serdes protocol maps initialized. As the first element of the map
isn't used for any device, so use it as the flag to indicate if the
map has been initialized.

aa36c84edf powerpc/mpc85xx: T104x: Add nand secure boot target
For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC.
In non-secure boot scenario from NAND, this address will map to CPC
configured as SRAM. But in case of secure boot, this default address
always maps to IBR (Internal Boot ROM).
The IBR code requires that the bootloader(U-boot) must lie in 0 to 3.5G
address space i.e. 0x0 - 0xDFFFFFFF.

For secure boot target from NAND, the text base for SPL is kept same as
non-secure boot target i.e. 0xFFFx_xxxx but the SPL U-boot binary will
be copied to CPC configured as SRAM with address in 0-3.5G(0xBFFC_0000)
As a the virtual and physical address of CPC would be different. The
virtual address 0xFFFx_xxxx needs to be mapped to physical address
0xBFFx_xxxx.

Create a new PBI file to configure CPC as SRAM with address 0xBFFC0000
and update DCFG SCRTACH1 register with location of Header required for
secure boot.

The changes are similar to
commit 467a40dfe3
    powerpc/mpc85xx: SECURE BOOT- NAND secure boot target for P3041

While P3041 has a 1MB CPC and does not require SPL. On T104x, CPC
is only 256K and thus SPL framework is used.
The changes are only applicable for SPL U-Boot running out of CPC SRAM
and not the next level U-Boot loaded on DDR.

4b689f02ff dm: gpio: MPC85XX GPIO platform data support
Define a platform data structure for the MPC85XX GPIO driver to allow
use of the driver without device tree. Users should define the GPIO
blocks for their platform like this:
  struct mpc85xx_gpio_plat gpio_blocks[] = {
         {
                 .addr = 0x130000,
                 .ngpios = 32,
         },
         {
                 .addr = 0x131000,
                 .ngpios = 32,
         },
  };

  U_BOOT_DEVICES(my_platform_gpios) = {
         { "gpio_mpc85xx", &gpio_blocks[0] },
         { "gpio_mpc85xx", &gpio_blocks[1] },
  };

This is intended to build upon the recent submission of the base
MPC85XX driver from Mario Six. We need to use that new driver
without dts support and this patch gives us that flexibility.
This has been tested on a Freescale T2080 CPU, although only the first
GPIO block.

07d31f8f98 dm: gpio: Add driver for MPC85XX GPIO controller
This patch adds a driver for the built-in GPIO controller of the MPC85XX
SoC (probably supporting other PowerQUICC III SoCs as well).

Each GPIO bank is identified by its own entry in the device tree, i.e.

gpio-controller@fc00 {
      #gpio-cells = <2>;
      compatible = "fsl,pq3-gpio";
      reg = <0xfc00 0x100>
}

By default, each bank is assumed to have 32 GPIOs, but the ngpios
setting is honored, so the number of GPIOs for each bank in configurable
to match the actual GPIO count of the SoC (e.g. the 32/32/23 banks of
the P1022 SoC).

The usual functions of GPIO drivers (setting input/output mode and output
value setting) are supported.

The driver has been tested on MPC85XX, but it is likely that other
PowerQUICC III devices will work as well.

73223f0e1b Kconfig: Move CONFIG_FIT and related options to Kconfig
There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.

Move these options to Kconfig and tidy up board configuration:

   CONFIG_FIT
   CONFIG_OF_BOARD_SETUP
   CONFIG_OF_SYSTEM_SETUP
   CONFIG_FIT_SIGNATURE
   CONFIG_FIT_BEST_MATCH
   CONFIG_FIT_VERBOSE
   CONFIG_OF_STDOUT_VIA_ALIAS
   CONFIG_RSA

Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.

Note: Masahiro's moveconfig.py script is amazing.

9e971632cd freescale: Remove CONFIG_DM from header files
Kconfig options must defined in the defconfig files. Since RSA_SOFTWARE_EXP
relies on CONFIG_DM, unless it is set in kconfig we cannot enable RSA.
Remove the hacks which enable CONFIG_DM in header files and update the
defconfig.

f698e9f39a powerpc/SECURE_BOOT: Add PAMU driver
PAMU driver basic support for usage in Secure Boot.
In secure boot PAMU is not in bypass mode. Hence to use
any peripheral (SEC Job ring in our case), PAMU has to be
configured.

The patch reverts commit 7cad2e38d6.

The Header file pamu.h and few functions in driver have been derived
from Freescale Libos.
