The 3CS support card (CONFIG_DCC_MICRO_SUPPORT_CARD) used to be used
very often before, but it is recently getting a minority. Swith to
the 1CS support card (CONFIG_PFC_MICRO_SUPPORT_CARD).Signed-off-by: Masahiro Yamada

Two support card variants are used with UniPhier reference boards:
- 1 chip select support card (original CPLD)
- 3 chip selects support card (ARIMA-compatible CPLD)Currently, the former is only supported on PH1-Pro4, but it can be
expanded to PH1-LD4, PH1-sLD8 with a little code change.Signed-off-by: Masahiro Yamada

PH1-Pro4 includes both EHCI and xHCI IP cores.
Unfortunately, U-Boot cannot enable EHCI and xHCI support
simultaneously. Some users may wish Super-Speed connection.

Each USB port corresponds to the following IP core:
port0: xHCI (0x65a00000) SS+HS
port1: xHCI (0x65c00000) HS (SS PHY is not implemented)
port2: EHCI (0x5a800100) HS
port3: EHCI (0x5a810100) HSSigned-off-by: Masahiro Yamada

Because uniphier_ehci_reset() is only called from ehci-uniphier.c,

Now UniPhier platform highly depends on Device Tree configuration
(CONFIG_OF_CONTROL is select'ed by Kconfig). Since the EHCI is only
used on main U-Boot, we can drop platform devices of the EHCI
controllers. We still keep UART platform devices because they might
be useful for SPL.Signed-off-by: Masahiro Yamada

Deassert the reset signal and provide the clock for STDMAC core.
This is necessary for the USB 2.0 host controllers.Signed-off-by: Masahiro Yamada
-
For all the UniPhier SoCs so far, the reset signal of the NAND core
is automatically deasserted after the PLL gets stabled.
(The bit 2 of SC_RSTCTRL is default to one.)This causes a fatal problem on the NAND controller of PH1-LD4.
For that SoC, the NAND I/O pins are not set up yet at the power-on
reset except the NAND boot mode. As a result, the NAND controller
begins automatic device scanning with wrong I/O pins and finally
hangs up.Actually, U-Boot dies after printing "NAND:" on the console unless
the boot mode latch detected the NAND boot mode.To work around this problem, reset the NAND core in SPL for non-NAND
boot modes. If CONFIG_NAND_DENALI is enabled, the reset signal is
deasserted again in U-Boot proper. At this time, I/O pins have been
correctly set up, the device scanning should succeed.Signed-off-by: Masahiro Yamada

Split the current clkrst_init() into two functions:
- early_clkrst_init(): called from SPL
Deassert the reset signals of the memory controller and some other
basic cores.- clkrst_init(): called from main U-boot
Deassert the reset signals that are necessary for the access to
peripherals etc.Signed-off-by: Masahiro Yamada

We do not have to set the LCR register every time we change the
baud-rate. We just need to set it up once in the probe function.Signed-off-by: Masahiro Yamada

For PH1-Pro4, the 8 bit write access to LCR register (offset = 0x11)
is not working correctly. As a side effect, it also modifies MCR
register (offset = 0x10) and results in unexpected behavior.Signed-off-by: Masahiro Yamada

This patch does the following:
1. The function names for encapsulation and decapsulation
were inconsitent in freescale's implementation and cmd_blob file.
This patch corrects the issues.
2. The function protopye is also modified to change the length parameter
from u8 to u32 to allow encapsulation and decapsulation of larger images.
3. Modified the description of km paramter in the command usage for better
readability.Signed-off-by: Gaurav Rana

Now CONFIG_SPL_BUILD is not defined in Kconfig, so
"!depends on SPL_BUILD" and "if !SPL_BUILD" are redundant.Signed-off-by: Masahiro Yamada
-
When Kconfig for U-boot was examined, one of the biggest issues was
how to support multiple images (Normal, SPL, TPL). There were
actually two options, "single .config" and "multiple .config".
After some discussions and thought experiments, I chose the latter,
i.e. to create ".config", "spl/.config", "tpl/.config" for Normal,
SPL, TPL, respectively.It is true that the "multiple .config" strategy provided us the
maximum flexibility and helped to avoid duplicating CONFIGs among
Normal, SPL, TPL, but I have noticed some fatal problems:[1] It is impossible to share CONFIG options across the images.
If you change the configuration of Main image, you often have to
adjust some SPL configurations correspondingly. Currently, we
cannot handle the dependencies between them. It means one of the
biggest advantages of Kconfig is lost.[2] It is too painful to change both ".config" and "spl/.config".
Sunxi guys started to work around this problem by creating a new
configuration target. Commit cbdd9a9737cc (sunxi: kconfig: Add
%_felconfig rule to enable FEL build of sunxi platforms.) added
"make *_felconfig" to enable CONFIG_SPL_FEL on both images.
Changing the configuration of multiple images in one command is a
generic demand. The current implementation cannot propose any
good solution about this.[3] Kconfig files are getting ugly and difficult to understand.
Commit b724bd7d6349 (dm: Kconfig: Move CONFIG_SYS_MALLOC_F_LEN to
Kconfig) has sprinkled "if !SPL_BUILD" over the Kconfig files.[4] The build system got more complicated than it should be.
To adjust Linux-originated Kconfig to U-Boot, the helper script
"scripts/multiconfig.sh" was introduced. Writing a complicated
text processor is a shell script sometimes caused problems.Now I believe the "single .config" will serve us better. With it,
all the problems above would go away. Instead, we will have to add
some CONFIG_SPL_* (and CONFIG_TPL_*) options such as CONFIG_SPL_DM,
but we will not have much. Anyway, this is what we do now in
scripts/Makefile.spl.I admit my mistake with my apology and this commit switches to the
single .config configuration.It is not so difficult to do that:
- Remove unnecessary processings from scripts/multiconfig.sh
This file will remain for a while to support the current defconfig
format. It will be removed after more cleanups are done.- Adjust some makefiles and Kconfigs
- Add some entries to include/config_uncmd_spl.h and the new file
scripts/Makefile.uncmd_spl. Some CONFIG options that are not
supported on SPL must be disabled because one .config is shared
between SPL and U-Boot proper going forward. I know this is not
a beautiful solution and I think we can do better, but let's see
how much we will have to describe them.- update doc/README.kconfig
More cleaning up patches will follow this.

At present defaults in arch-specific Kconfig files are ignored if the
top-level item comes ahead of it in include order. This means that it is
not possible to have a U-Boot default that architectures and boards can
override. This does not seem very useful.Move the include earlier to support this.
