With this change Synopsys DesignWare SDP board is switched to driver
model for both serial port (serial_dw) and Ethernet (Designware GMAC).This simplifies include/configs/axs101.h and allows for reuse of Linux's
Device Tree description.For simplicity Linux's .dts files are not blindly copied but only very
few extracts of them are really used (those that are supported in U-Boot
at the moment).Signed-off-by: Alexey Brodkin

It turned out with some boards (FPGA firmwares?) and cards combos
current clock settings doesn't work as expected leading to strange
card freezes or corrupted data being read from the card.Especially this was seen with Transcend 2Gb cards shipped as a part of
ARC SDP:
----------------->8---------------
AXS# mmcinfo
Device: Synopsys Mobile storage
Manufacturer ID: 74
OEM: 4a60
Name: SDC
Tran Speed: 50000000
Rd Block Len: 512
SD version 3.0
High Capacity: No
Capacity: 1.8 GiB
Bus Width: 4-bit
Erase Group Size: 512 Bytes
AXS# fatload mmc 0
** Unrecognized filesystem type **
----------------->8---------------With this change that problem is fixed.
Note "Tran Speed" above doesn't match clock value set in DW MMC.
It is max value for card's speed class.Signed-off-by: Alexey Brodkin

With new SMP-enabled CPUs with ARC HS38 cores and corresponding support
in Linux kernel it's required to add basic SMP support in U-Boot.Currently we assume the one and only core starts execution after
power-on. So most of things in U-Boot is handled in UP mode.But when U-Boot is used for loading and starting Linux kernel right
before jumping to kernel's entry point U-Boot:
[1] Sets all slave cores to jump to the same address [kernel's entry
point]
[2] Really starts all slav coresIn ARC's implemetation of SMP in Linux kernel all cores are supposed to
run the same start-up code. But only core with ID 0 (master core)
processes further while others are looping waiting for master core to
complete some initialization.That means it's safe to un-pause slave cores and let them execute kernel
- they will wait for master anyway.Signed-off-by: Alexey Brodkin

There're 2 versions of motherboards that could be used in ARC SDP.
The only important difference for U-Boot is different NAND IC in use:
[1] v2 board (we used to support up until now) sports MT29F4G08ABADAWP
while
[2] v3 board sports MT29F4G16ABADAWPThey are almost the same except data bus width 8-bit in [1] and 16-bit
in [2]. And for proper support of 16-bit data bus we have to pass
NAND_BUSWIDTH_16 option to NAND driver core - which we do now knowing
board type we're running on.Signed-off-by: Alexey Brodkin

With the most recent board firmware correct SDIO clock is 50MHz as
opposed to 25 MHz before.Also set max frequency of MMC data exchange equal to SDIO clock -
because there's no way to transfer data faster than interface clock.Signed-off-by: Alexey Brodkin

This change allows to keep board description clean and minimalistic.
This is especially helpful if one board may house different CPUs with
different features.It is applicable to both FPGA-based boards or those that have CPUs
mounted on interchnagable daughter-boards.Signed-off-by: Alexey Brodkin

Both ARCangel4 and AXS10x are FPGA-based boards so they may have
different CPUs. For now we have only 1 option (ARC700) and we define
this as default in arch Kconfig.Signed-off-by: Alexey Brodkin

Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.We can delete the ones in arch and board Kconfig files.
This commit can be easily reproduced by the following command:
find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
N
s/\n[[:space:]]*string//

We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.Signed-off-by: Masahiro Yamada

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board(This commit was automatically generated by a conversion script
based on boards.cfg)In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.Signed-off-by: Masahiro Yamada

CPU sets DMA buffer descriptors with data required for inetrnal DMA such as:
* Ownership of BD
* Buffer size
* Pointer to data buffer in memoryThen we need to make sure DMA engine of NAND controller gets proper data.
For this we flush buffer rescriptor.Then we're ready for DMA transaction.
