484a878273 arm: spear: fix enabling of SSP2 clock
The SSP2 clock is at bit 6 in the register, so the value is 0x40 unlike
the current 0x70 which enables the clock of UART2, SSP1 and SSP2.

ac47fbee6d arm: spear: enable SSP1, 2 and 3 clocks when SPI controller driver is built
SPI controllers SSP1, 2 and 3 require to enable their respective clocks.
Let's enable them only when the SPI controller driver is built.

d2d908d258 arm: spear: enable GPIO3 and 4 clocks when the GPIO controller driver is built
There are multiple GPIOs that can be used with the same driver depending
on the CONFIG_GPIO_BASE defined in the controller driver.

GPIO3 and 4 require a clock to be enabled so let's enable them when the
driver is built.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

da53ba0219 arm: spear: Add command to switch between 1-bit HW ECC and SW BCH4
This patch adds the "nandecc" command to switch between the SPEAr600 internal
1-bit HW ECC and the 4-bit SW BCH4 ECC. This can be needed to support NAND
chips with a stronger ECC than 1-bit, as on the x600. And to dynamically
switch between both ECC schemes for backwards compatibility.

4ae8bc4392 SPL: ARM: spear: Add SPL support for SPEAr600 platform
This patch adds SPL support for SPEAr600. Currently only SNOR
(Serial NOR) flash support is included. Other boot devices
(NAND, MMC, USB ...) may be added with later patches.

Tested on the STM SPEAr600 evaluation and x600 SPEAr600 boards.

962d026b6a SPEAr: Add basic arch related support for SPEAr SoCs
Earlier, architecture specific init code was mixed with board initialization
code in board/spear/... This patch updates architecture support for SPEAr in
latest u-boot and prints the SoC information.

819833af39 Move architecture-specific includes to arch/$ARCH/include/asm
This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
