Add support for WinLink E850-96 board [1]. It's based on Exynos850 SoC
and follows 96boards specification, so it's compatible with 96boards
mezzanine boards [2]. This patch enables next features:
* Serial console
* USI
* PMU (muxing AP UART path)
* Pinctrl
* Clocks
* Timer (ARMv8 architected)
* Reset control
It's quite a minimal enablement. Features like MMC, USB and Ethernet
will be enabled later.
The rationale for config values is as follows:
* TEXT_BASE = 0xf8800000
That's where BL2 loads the U-Boot payload, so TEXT_BASE must be
exactly this value. Overall the memory map is designed in a way to
keep the bootloader in the upper 128 MiB area of RAM, which is
0xf8000000..0xffffffff. That includes bootloader's code, stack,
data, heap, MMU tables, etc. All the memory below that 128 MiB chunk
can be used for storing boot images (0x80000000..0xf8000000).
* CUSTOM_SYS_INIT_SP_ADDR = 0xf8c00000
Just 4 MiB above the TEXT_BASE address, to leave enough space for
U-Boot code and stack itself (grows downwards).
* SYS_LOAD_ADDR = 0x80000000
The beginning of RAM. That's where Linux kernel image must be
loaded.
* SYS_MALLOC_LEN = 0x81f000
8 MiB for malloc() + ENV_SIZE (128 KiB)
* SYS_MALLOC_F_LEN = 0x4000
Increase malloc() pool size available before relocation from 8 KiB
(default) to 16 KiB. Otherwise "alloc space exhausted" message
appears in U-Boot log during board_init_f() stage. There are next
reasons for doing so:
1. Having "bootph-all" flags in some dts nodes leads to binding
those during pre-relocation stage, and binding (DM) uses
dynamic memory allocation
2. clk-exynos850 driver uses CCF clocks, which in turn use dynamic
memory allocation
Device tree file was imported from Linux kernel. All nodes and boot
phase flags added in exynos850-e850-96-u-boot.dtsi are only needed to
enable serial console:
* oscclk -> cmu_top -> cmu_peri: generate UART/USI clocks
* pinctrl_alive and uart1_pins: needed to mux UART pins
* pmu_system_controller: configures AP UART path to uart1_pins
* usi_uart: configures USI block to operate as a UART protocol
* serial_0: enables serial console (UART)
