89038264bb mach-imx: bootaux: add dcache flushing before enabling M4
This patch fixes the issue with broken bootaux command,
when M4 binary is loaded and data cache isn't flushed
before M4 core is enabled.

Reproducing:
> tftpboot ${loadaddr} ${board_name}/hello_world.bin
> cp.b ${loadaddr} 0x7F8000 $filesize
> bootaux 0x7F8000

c35b19531d ARM: mx6: ddr: Add support for iMX6SX
This patch adds support for iMX6SX MMDC into the DDR calibration
code. The only difference between MX6DQ and MX6SX is that the SX
has 2 SDQS registers, while the DQ has 8.

736b491f31 ARM: mx6: ddr: Make debug prints work with tiny printf
The %08X format returns just zeroes with tiny printf, which is

40109f4d7e arm: mach-k3: Enable WA for R5F deadlock
On K3 devices there are 2 conditions where R5F can deadlock:
1.When software is performing series of store operations to
  cacheable write back/write allocate memory region and later
  on software execute barrier operation (DSB or DMB). R5F may
  hang at the barrier instruction.
2.When software is performing a mix of load and store operations
  within a tight loop and store operations are all writing to
  cacheable write back/write allocates memory regions, R5F may
  hang at one of the load instruction.

To avoid the above two conditions disable linefill optimization
inside Cortex R5F which will make R5F to only issue up to 2 cache
line fills at any point of time.

05767707a8 dts: am335x-brsmarc1/xre1: insert phy_id again
commit 3b3e8a37d3
("arm: dts: am335x: sync cpsw/mdio/phy with latest linux - drop phy_id")

did sync with recent linux kernel and replaced therefore the 'phy_id'
property with a phy-handle pointing to the mdio.

This is OK for linux, but introduces trouble with the already running
vxWorks on this target.

So this commit here re-inerts the phy_id property beside the phy-handle
property to be compatible with both.

90ae281437 riscv: add option to wait for ack from secondary harts in smp functions
Add a wait option to smp_call_function() to wait for the secondary harts
to acknowledge the call-function request. The request is considered to
be acknowledged once each secondary hart has cleared the corresponding
IPI.

As part of the call-function request, the secondary harts invalidate the
instruction cache after clearing the IPI. This adds a delay between
acknowledgment (clear IPI) and fulfillment (call function) of the
request. We want to use the acknowledgment to be able to judge when the
request has been completed. Remove the delay by clearing the IPI after
cache invalidation and just before calling the function from the
request.

8b3e97badf riscv: add functions for reading the IPI status
Add the function riscv_get_ipi() for reading the pending status of IPIs.
The supported controllers are Andes' Platform Level Interrupt Controller
(PLIC), the Supervisor Binary Interface (SBI), and SiFive's Core Local
Interruptor (CLINT).

444c46413f riscv: Fix clear bss loop in the start-up code
For RV64, it will use sd instruction to clear t0
register, and the increament will be 8 bytes. So
if the difference between__bss_strat and __bss_end
was not 8 bytes aligned, the clear bss loop will
overflow and acks like system hang.

Fix two wrong settings of andes plic driver as below:

2. Declaring the en variable in enable_ipi() as unsigned int instead of
   int can help to fix wrong plic enabling setting in RV64.
