Describe minimal DT boot machine details for AM43x based SoC's. AM43x
SoC's are ARM Cortex-A9 based with one core. AM43x is similar to
AM335x w.r.t L4 PER/WKUP memory map. AM43x has a sync timer, here that
is being used as clocksource, while 1ms dmtimer as clockevent.Signed-off-by: Ankur Kishore

Minimal early init - PRCM initialization not yet taken care.
Control module is similar (base address, feature register etc.) as
that of AM335x, while PRCM base address is different. Instead of
adding a new header file for AM43x, PRCM base address is added in
AM335x header file as it is similar to it to a large extent.Signed-off-by: Afzal Mohammed

…l/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt:
"This contains 4 fixes.The first two fix the case where full RCU debugging is enabled,
enabling function tracing causes a live lock of the system. This is
due to the added debug checks in rcu_dereference_raw() that is used by
the function tracer. These checks are also traced by the function
tracer as well as cause enough overhead to the function tracer to slow
down the system enough that the time to finish an interrupt can take
longer than when the next interrupt is triggered, causing a live lock
from the timer interrupt.Talking this over with Paul McKenney, we came up with a fix that adds
a new rcu_dereference_raw_notrace() that does not perform these added
checks, and let the function tracer use that.The third commit fixes a failed compile when branch tracing is
enabled, due to the conversion of the trace_test_buffer() selftest
that the branch trace wasn't converted for.The forth patch fixes a bug caught by the RCU lockdep code where a
rcu_read_lock() is performed when rcu is disabled (either going to or
from idle, or user space). This happened on the irqsoff tracer as it
calls task_uid(). The fix here was to use current_uid() when possible
that doesn't use rcu locking. Which luckily, is always used when
irqsoff calls this code."* tag 'trace-fixes-v3.10-rc3-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:

From Shawn Guo, mxs fixes for 3.10:
- Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no
interrupt in icoll_handle_irq() becomes insane, because 0x7f is an
valid interrupt number, the irq of gpio bank 0. That unnecessary
polling results in the driver not detecting when irq 0x7f is active
which makes the machine effectively dead lock. The fix removes the
interrupt poll loop and allows usage of gpio0 interrupt without an
infinite loop.* tag 'mxs-fixes-3.10' of git://git.linaro.org/people/shawnguo/linux-2.6:

From Shawn Guo, imx fixes for 3.10, take 2:
- One device tree fix for all spi node to have per clock added.
The clock is needed by spi driver to calculate bit rate divisor.
The spi node in the current device trees either does not have the
clock or is defined as dummy clock, in which case the driver probe
will fail or spi will run at a wrong bit rate.- Two imx6q clock fixes, which correct axi_sels and ldb_di_sels.

If the early MMU mapping of the UART happens to get booted out of the
TLB between the start of paging_init() and when we finally re-add the
UART at the very end of s3c_init_cpu(), we'll get a hang at bootup if
we've got early_printk enabled. Avoid this hang by calling
debug_ll_io_init() early.Without this patch, you can reliably reproduce a hang when early
printk is enabled by adding flush_tlb_all() at the start of
exynos_init_io(). After this patch the hang goes away.Signed-off-by: Doug Anderson

Printing low-level debug messages make an assumption that the specified
UART port has been preconfigured by the bootloader. Incorrectly
specified UART port results in system getting stalled while printing the
message "Uncompressing Linux... done, booting the kernel"
This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since
the UART port might different for different board, it is not possible to
specify it correctly for every board that use a common defconfig file.Calling this print subroutine only when DEBUG_LL fixes the problem. By
disabling DEBUG_LL in default config file, we would be able to boot
multiple boards with different default UART ports.With this current approach, we miss the print "Uncompressing Linux...
done, booting the kernel." when DEBUG_LL is not defined.Signed-off-by: Tushar Behera
