843a76b66b MIPS: start.S: emulate REVISION register for qemu-malta
On the origial Malta boards the REVISION register is
accessible at the 0x1fc00010 address. The contents of
this register gives information about the revision
of the Malta and Core Boards.

This register is used by the Linux kernel to identify
the actual board it is running on. However the register
is not emulated properly by Qemu, so put a hardcoded
value into the flash to make Linux work.

4fc9670513 nds32: ag101/ag102: Fix setting lastdec and now values
The timer3 counter unit for lastdesc and now values are inconsistent in current
code. The unit of "readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2)" is
second. However, CONFIG_SYS_HZ is defined as 1000 in board config file.
This means the accuracy of "lastdec" and "now" should be in millisecond,
thus fix the equation to set lastdec and now variables accordingly.

bea2868f5e nds32: introduce macros for bit manipulation
U-Boot does not compile for the adp-ag101 boards since
commit f6c3b34697 (mmc:
update Faraday FTSDC010 for rw performance)

The driver assumes that the bit manipulation macros
are provided by all architectures. This is not the
case for nds32 and it causes a build error like this:

  ftsdc010_mci.c: In function 'ftsdc010_clkset':
  ftsdc010_mci.c:118: warning: implicit declaration of function 'setbits_le32'

The patch adds bit manipulation macros for the

are copied from the ARM implementation.

4) Made spl_boot.c and tzpc_init.c common for both exynos4 and exynos5.

6) exynos-uboot-spl.lds made common across SMDKV310, Origen and SMDK5250.

The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs.
These SoCs have different gpio count but currently omap_gpio driver uses hard

1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h.
2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5.

58c86c7d1d am33xx: fix the ddr_cmdtctrl structure
Fix the wrong mapping between the DDR I/O control registers on AM33XX
SoCs and the software representation in the SPL code.
The most recent public TRM defines the following DDR I/O control registers
offsets:
 * ddr_cmd0_ioctrl : offset 0x44E11404
 * ddr_cmd1_ioctrl : offset 0x44E11408
 * ddr_cmd2_ioctrl : offset 0x44E1140C
 * ddr_data0_ioctrl: offset 0x44E11440
 * ddr_data1_ioctrl: offset 0x44E11444

While the struct ddr_cmdtctrl has also some reserved bits in the beginning.
The struct is mapped to the address 0x44E11404. As a result "cm0ioctl" points
to the ddr_cmd1_ioctrl register, "cm1ioctl" to the ddr_cmd2_ioctrl and etc.
Registers ddr_cmd0_ioctrl and ddr_data0_ioctrl are never configured because
of this mapping mismatch.

983c72f479 Clarify bootm OS arguments
At present the arguments to bootm are processed in a somewhat confusing
way. Sub-functions must know how many arguments their calling functions
have processed, and the OS boot function must also have this information.
Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
the same way.

Adjust the code so that arguments are removed from the list before calling
a sub-function. This means that all functions can know that argv[0] is the
first argument of which they need to take notice.

finally stoped depending on the address is equal to the _bss_end. If the end

1. The reset action stoped depending on the reset address is greater
than or equal the end address of the BSS.
2. The end address of the BSS should be 4byte aligned. Because the reset unit
is 4 Bytes.

5df572f013 powerpc/mpc85xx: support application without resetvec segment in the linker script
For SD/SPI 2-stage bootloader, the On-Chip Rom code loads the SPL into L2 SRAM,
then jump to it to begin execution. After that, the SPL loads the final uboot
image into DDR, then jump to it to begin execution. The segment .resetvec in
the SPL and in final U-boot is useless.

So, add new symbols CONFIG_SYS_MPC85XX_NO_RESETVEC for this application.
If CONFIG_SYS_MPC85XX_NO_RESETVEC is set, the segment .resetvec is excluded
and the segment .bootpg is placed in the previous 4K of the segment .text.

Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable

into the file arch/powerpc/include/asm/config_mpc85xx.h.

Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to
"CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from

dbc000bfb5 ARM: tegra: only enable SCU on Tegra20
The non-SPL build of U-Boot on Tegra only runs on a single CPU, and
hence there is no need to enable the SCU when running U-Boot. If an
SMP OS is booted, and it needs the SCU enabled, it will enable the SCU
itself. U-Boot doing so is redundant.

The one exception is Tegra20, where an enabled SCU is required for some
aspects of PCIe to work correctly.

Some Tegra SoCs contain CPUs without a software-controlled SCU. In this
case, attempting to turn it on actively causes problems. This is the case
for Tegra114. For example, when running Linux, the first (or at least
some very early) user-space process will trigger the following kernel
message:

Unhandled fault: imprecise external abort (0x406) at 0x00000000

This is typically accompanied by that process receving a fatal signal,
and exiting. Since this process is usually pid 1, this causes total
system boot failure.

we've always been placing our stack outside of the download image area

correct the max size test to be the ROM defined top of the download area

39bdaff4f4 SECURE BOOT - Removed deletion of TLB entries code
Boot ROM code creates TLB entries for 3.5G space before entering
the u-boot. Earlier we were deleting these entries after early
initialization of CPU. In recent past, code has been added
to invalidate all these entries before relocation of u-boot code.
So this code to delete TLB entries after CPU initialization
is no longer required.

Sparc only really sets up the ramdisk, but we should still use
image_setup_linux() so that setup is common across all architectures
that use the FDT.

Cover-letter
Introduce a common image_setup_linux() function
This series continues the work to tidy up the image code. Each
architecture has its own code for setting up ready for booting linux.
An attempt is made here to unify these in a single image_setup_linux()
function.

The part of the image code that deals with FDT is split into image-fdt.c
and a few tweaks are added to make FIT images more viable in SPL.

da34aae5fb bfin: Move gpio support for bf54x and bf60x into the generic driver folder.
The gpio spec for bf54x and bf60x differ a lot from the old gpio driver for bf5xx.
A lot of machine macros are used to accomodate both code in one gpio driver.
This patch split the old gpio driver and move new gpio2 support to the generic
gpio driver folder.

- To enable gpio2 driver, macro CONFIG_ADI_GPIO2 should be defined in the board's
config header file.
- The gpio2 driver supports bf54x, bf60x and future ADI processors, while the
older gpio driver supports bf50x, bf51x, bf52x, bf53x and bf561.

2e2ed3f4ff Blackfin: adjust asm constraints with NMI workaround
Newer gcc versions will sometimes use a Preg when "r" constraints, but
that'll fail if we use an Ireg in the assignment.  So force the code
to always use a Dreg.

This also fixes early boot crashes for older Blackfin parts when compiled
with gcc-4.5.  This version ends up selecting the same register for the
input and output variables which corrupts the output assignment triggering
an exception.

0b1b60c779 ARM: OMAP5: Fix warm reset with USB cable connected
Warm reset on OMAP5 freezes when USB cable is connected.
Fix requires PRM_RSTTIME.RSTTIME1 to be programmed
with the time for which reset should be held low for the
voltages and the oscillator to reach stable state.

There are 3 parameters to be considered for calculating
the time, which are mostly board and PMIC dependent.
-1- Time taken by the Oscillator to shut + restart
-2- PMIC OTP times
-3- Voltage rail ramp times, which inturn depends on the
PMIC slew rate and value of the voltage ramp needed.

In order to keep the code in u-boot simple, have a way
for boards to specify a pre computed time directly using
the 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC'
option. If boards fail to specify the time, use a default
as specified by 'CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC' instead.
Using the default value translates into some ~22ms and should work in
all cases.
However in order to avoid this large delay hiding other bugs,
its recommended that all boards look at their respective data
sheets and specify a pre computed and optimal value using
'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC'

In order to help future board additions to compute this
config option value, add a README at doc/README.omap-reset-time
which explains how to compute the value. Also update the toplevel
README with the additional option and pointers to
doc/README.omap-reset-time.

3) Start Levelling procedure.
