Use asmlinkage defined in include/linux/linkage.h if necessary.
Actually no ARM board uses asmlinkage, so this commit has no impact.Signed-off-by: Masahiro Yamada
Cc: Albert ARIBAUD -
Commit 65dd74a674d6 (x86: ivybridge: Implement SDRAM init) introduced
x86-specific asmlinkage into arch/x86/include/asm/config.h.Commit ed0a2fbf14f7 (x86: Add a definition of asmlinkage) added the
same macro define again, this time, into include/common.h.
(Please do not add arch-specific stuff to include/common.h any more;
it is already too cluttered.)The generic asmlinkage is defined in . If you want
to override it with an arch-specific one, the best way is to add it
to like Linux Kernel.Signed-off-by: Masahiro Yamada

Enabled byte program support for sst flashes in sf.
Few controllers will only support BP, so this patch gives
a tx transfer flag to set the BP so-that sf will operate
on byte program transfer.A new TX operation mode SPI_OPM_TX_BP is introduced for such SPI
controller to use byte program op for SST flash.Signed-off-by: Jagannadha Sutradharudu Teki

If the MMC_MODE_DDR_52MHz flag is set in card capabilities bitmask,
it is never cleared, even if switching to DDR mode fails, and if
the controller driver uses this flag to check the DDR mode, it can
take incorrect actions.Also, DDR related checks in mmc_startup() incorrectly handle the case
when the host controller does not support some bus widths (e.g. can't
support 8 bits), since the host_caps is checked for DDR bit, but not
bus width bits.This fix clearly separates using of card_caps bitmask, having there
the flags for the capabilities, that the card can support, and actual
operation mode, described outside of card_caps (i.e. bus_width and
ddr_mode fields in mmc structure). Separate host controller drivers
may need to be updated to use the actual flags. Respectively,
the capabilities checks in mmc_startup are made more correct and clear.Also, some clean up is made with errors handling and code syntax layout.

This converts all Tegra boards over to use driver model for I2C. The driver
is adjusted to use driver model and the following obsolete CONFIGs are
removed:- CONFIG_SYS_I2C_INIT_BOARD
- CONFIG_I2C_MULTI_BUS
- CONFIG_SYS_MAX_I2C_BUS
- CONFIG_SYS_I2C_SPEED
- CONFIG_SYS_I2CThis has been tested on:
- trimslice (no I2C)
- beaver
- Jetson-TK1It has not been tested on Tegra 114 as I don't have that board.

Nyan-big is a Tegra124 clamshell board that is very similar to venice2, but
it has a different panel, the sdcard cd and wp sense are flipped, and it has
a different revision of the AS3722 PMIC.This is the Acer Chromebook 13 CB5-311-T7NN (13.3-inch HD, NVIDIA
Tegra K1, 2GB). The display is not currently supported, so it should
boot on other nyan-based Chromebooks also, but only the device tree for
nyan-big is provided here.The device tree file is from Linux but with features removed which are
unlikely to be supported in U-Boot soon (regulators, pinmux). Also the
addresses are updated to 32-bit.Signed-off-by: Allen Martin

The functions error's numbers are standarized - but the error
messages are not.The errors are often handled with unclear error messages,
so why not use an errno standarized messages.Advantages:
- This could decrease the binary size.
- Appended with a detailed information,
the error message will be clear.This commit introduces new function:
- const char *errno_to_str(int errno)The functions returns a pointer to the errno corresponding text message:
- if errno is null or positive number - a pointer to "Success" message
- if errno is negative - a pointer to errno related messageSigned-off-by: Przemyslaw Marczak

LS1 has 4 SMMUs for address translation of the masters. All the
SMMUs' stream IDs are 8-bit. The address translation depends on the
stream ID of the incoming transaction.
Each master has unique stream ID assigned to it and is configurable
through SCFG registers. The stream ID for the masters is identical
and share the same register field of STREAM ID registers.Signed-off-by: Xiubo Li

The Central Security Unit (CSU) allows secure world software to
change the default access control policies of peripherals/bus
slaves, determining which bus masters may access them. This
allows peripherals to be separated into distinct security domains.
Combined with SMMU configuration of the system masters privileges,
these features provide protection against indirect unauthorized
access to data.For now we configure all the peripheral access permissions as R/W.
