Rob Herring 0f7cf3803f ARM: highbank: avoid bss write in timer_init
The timer_init function is called before relocation and writes to bss data
were corrupting relocation data. Fix this by removing the call to
reset_timer_masked. The initial timer count should be 0 or near 0 anyway,
so initializing the variables are not needed.

Rob Herring 0f5141e9c5 ARM: move interrupt_init to before relocation
interrupt_init also sets up the abort stack, but is not setup before
relocation. So any aborts during relocation will hang and not print out
any useful information. Fix this by moving the interrupt_init to after
the stack setup in board_init_f.

Axel Lin 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.

U-Boot does not compile for the adp-ag101 boards since
commit f6c3b34697 (mmc:

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:

are copied from the ARM implementation.

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.

 * 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.

Commit 35fc84fa1f broke bootm on avr32. It
requires to call do_bootm_linux() with flag set to BOOTM_STATE_OS_PREP before
calling it again with flag set to BOOTM_STATE_OS_GO.
Fix this by allowing flag set to BOOTM_STATE_OS_PREP, this however will

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.

Tom Warren 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.
