ARM: debug: stm32: add UART early console support for STM32MP1

2020-03-13T16:05:07+00:00

Add support of early console for STM32MP1. Default UART instance is UART4,
but other UART instances can be configured by setting physical and virtual
base addresses in menuconfig.

ARM: debug: stm32: add UART early console support for STM32H7

2020-03-13T16:05:07+00:00

Add support of early console for STM32H7. Default UART instance is USART1,
but other UART instances can be configured by setting physical and virtual
base addresses in menuconfig.

ARM: debug: stm32: add UART early console configuration for STM32F4

2020-03-13T16:05:07+00:00

Early console is hardcoded on USART1 in current implementation.
With this patch, default UART instance is USART1, but other UART instances
can be configured by setting physical and virtual base addresses in
menuconfig.

ARM: brcmstb: Add debug UART entry for 7216

2019-12-20T18:54:05+00:00

7216 has the same memory map as 7278 and the same physical address for
the UART, alias the definition accordingly.

Renesas ARM SoC updates for v5.4

  - Low-level debugging support for RZ/A2M.

ARM: debug-ll: Add support for r7s9210

2019-08-21T09:15:26+00:00

Enable low-level debugging support for RZ/A2M (r7s9210).

The RZA2MEVB board uses either SCIF2 (SDRAM enabled) or SCIF4 (HyperRAM
only) for the serial console.

Note that "SCIFA" serial ports on RZ/A2 SoCs use a compressed register
layout, hence add support for that to renesas-scif.S.

2019-08-14T13:37:17+00:00

This is a slew of Ux500 updates for the v5.4 kernel cycle:

- Stop populating the PRCMU devices from the core CPU
  file, it works just fine at device_initcall() level.

- Add a missing of_node_put() in the core file.

- Simplify the debug UART code.

- Add myself to MAINTAINERS

ARM: remove ks8695 platform

2019-08-14T13:03:52+00:00

ks8695 is an older SoC originally made by Kendin, which was later acquired
by Micrel, and subsequently by Microchip.

The platform port was originally contributed by Andrew Victor and Ben
Dooks, and later maintained by Greg Ungerer.

When I recently submitted cleanups, but Greg noted that the platform no
longer boots and nobody is using it any more, we decided to remove it.

ARM: ux500: simplify and move debug UART

2019-07-23T08:44:14+00:00

The debug UART code defined three different virtual addresses
while only one is ever used. Get rid of this, and move the
UART remapping to 0xfffe8000 where DTCM reside on some platforms
but not on Ux500, so it can be reused moving the UART out of the
vmalloc area.

Pull ARM SoC platform updates from Olof Johansson:
 "SoC platform changes. Main theme this merge window:

   - The Netx platform (Netx 100/500) platform is removed by Linus
     Walleij-- the SoC doesn't have active maintainers with hardware,
     and in discussions with the vendor the agreement was that it's OK
     to remove.

   - Russell King has a series of patches that cleans up and refactors
     SA1101 and RiscPC support"
