This patch adds basic board support for SMDK5420 board.
These patches are tested for booting fine on EVT1 SMDK5420.
Changes in V2:
- Corrected a compilation issue for SMDK5420.
Changes in V3:
- Add patch to support variable size SPL support
- Add patch to disable SMU for eMMC.
Changes in V4:
- Added check for MAX77686 pmic compilation.
- Added correct calculation of gpio based addresses.
- Rebased on the latest u-boot code.
- Removed patches for UART and TZPC changes as
they were not needed.
- Added flag to disable SMU for eMMC.
Changes in V5:
- Moved functions board_mmc_init and board_eth_init
to common/board.c in case of device tree support.
Changes in V6:
- Rebased on the latest mainline branch.
- Moved the definitions for SMU to arch/arm dwmmc.h
Rajeshwari S Shinde (10):
EXYNOS5: Create a common board file
Exynos5420: Add base addresses for 5420
Exynos5420: Add clock initialization for 5420
Exynos5420: Add DDR3 initialization for 5420
Exynos5420: Add support for 5420 in pinmux and gpio
Exynos5420: Add base patch for SMDK5420
DTS: Add dts support for SMDK5420
Config: Add initial config for SMDK5420
SPL: EXYNOS: Prepare for variable size SPL support
DWMMC: SMDK5420: Disable SMU for eMMC

To: u-boot
When variable size SPL is used, the BL1 expects the SPL to be
encapsulated differently: instead of putting the checksum at a fixed
offset in the SPL blob, prepend the blob with a header including the
size and the checksum.
The enhancements include
- adding a command line option, '--vs' to indicate the need for the
variable size encapsulation
- padding the fixed size encapsulated blob with 0xff instead of random
memory contents
- do not silently truncate the input file, report error instead
- no need to explicitly closing files/freeing memory, this all happens
on exit; removing cleanups it makes code clearer
- profuse commenting
- modify Makefile to allow enabling the new feature per board

The name of exynos5 common file can't be just "board.c" since it is
common only for Exynos5 boards and is placed in Samsung common.
We have few Exynos4 boards in u-boot and in future we can introduce
common board file for them too.
So it is better to add some additional word to this file name. This also
needs to change config name or add checking SOC version in common Makefile.
Thank you,

I'm not sure that you understand my intention.
You want to introduce:
board/samsung/common/board.c - with only Exynos5 code
I mean that it should looks like this, e.g:
"board/samsung/common/board_exynos4.c" - common code for all Exynos 4
"board/samsung/common/board_exynos5.c" - common code for all Exynos 5
since there is some duplicated code in Exynos4 boards that can be moved
to one common file in the future.
Do you understand my intention now?
Regards

Yes I understood your intention, but had a question cannot we use the
same file board.c for exynos4 and exynos5 too.
Since both have most of functions similar like board_init, dram_init,
board_uart_init and so on.
If u still feel that exynos4 and exynos5 have lots of functions
different in board/samsung we can create a seperate file. I was hoping
the same board.c could be reused for exynos4 also.

Ah, ok. This is good idea with the one common file. Then we will have
board files with strict board dependent functions. So I don't have any
objections jet.

OK. I understood SPI4 is different with other SPIs.
but, it was another context.
just break and move it to out of this switch..case.

Will remove gpio_func, but if I dont set start to 0 I get following error:
pinmux.c: In function ?exynos_pinmux_config?:
pinmux.c:173:20: warning: ?start? may be used uninitialized in this

I know, but this if statement for proid..
then, you should use same statement.
you can do this.
else if (proid_is_exynos5250() || prois_is_exynos5420())
or
if (cpu_is_exynos4()) {
if (proid_is....) {
} else if (proid_is....) {
}
} else if (cpu_is_exynos5()) {
.....
}
Thanks,
