* ARM: Rockchip: Add rk3568 BananaPi R2 Pro board supportFrank Wunderlich2022-02-119-0/+736
| | | | | | | | | | | | | | | | | | This adds support for the BananaPi R2 Pro board. It is basicly a copy of rk3568 evb board but with slightly modified DTS. Added GPIO-Leds to dts and modified the hw-detection a bit. Tested features so far are: - 1st stage booting - Network - SD card and Emmc - usb (1.1 and 3 work, usb2 not working) - power LED (green) Signed-off-by: Frank Wunderlich <frank-w@public-files.de> Link: https://lore.barebox.org/20220211091354.11573-1-linux@fw-web.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TinyEMU's RISC-V machine emulates a 64K SRAM at address 0. First 4K page is unused, then a maximum of 0x40 bytes for boot ROM (trampoline that passes FDT), then the FDT. The remainder of the 64K is unused. Make use of that space for storing state and environment. We start the mtd-ram at 0x1000 to easily allow for a faulting zero page.

We already support Virt I/O console, but the HTIF is easier to support for very early low level debugging. Add DEBUG_LL support to facilitate using it. Note: when using a framebuffer, riscvemu doesn't allocate a default console, so barebox calling into HTIF will segfault the emulator.

The Raspberry Pi 4 support will be ARM64. To allow it to reuse the existing low-level code, use the new ENTRY_FUNCTION_WITHSTACK, which will set up stack appropriately for both ARM32 and ARM64.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The point of ENTRY_FUNCTION is to write the entry point in C. Due to lack of __naked on ARM64, the start of the entry point will have prologue using stack and it's not possible to set up the stack safely without branching into non-inline assembly[0]. On ARM32, where we got __naked, we have the potential for a different problem: If BootROM sets up stack for us and we branch to a naked function, which doesn't set up its own stack, compiler may decide to spill local variables overwriting instructions it had already run[1]. For code reuse between ARM and ARM64, it would be nice to use the same entry point structure for both. Currently, the only way is to write it in non-inline assembly using the ENTRY_PROC macro. This introduces another way: the ARM64 barebox header has enough space for 8 instructions of which 5 are unused (2 instructions compiler prologue + 1 instruction to jump after the header), we could place a stack setup routine there to avoid having to write a separate assembly file. For ARM32, we just call arm_setup_stack and branch out directly after, freeing board porters of the burden of getting it right. Add a new ENTRY_FUNCTION_WITHSTACK to realize this.

We have three users in-tree for outl: * drivers/serial/serial_ns16550_pci.c only for handling a Quatech qurik, which probably no one ever needed * drivers/serial/serial_ns16550.c For platform drivers with a 4 byte I/O port resource. Only possible user is x86 and that has a 1 byte I/O port resource. Thus no one used this either. * drivers/watchdog/itco_wdt.c Here it indeed triggers a bug, although in my testing the WDAT was functional without. Fix this up so new code doesn't have to track this down.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 130c7d6715e9 ("ARM: beaglebone: init MPU speed to 800Mhz") causes warm reboot from within Linux v5.14.0 to no longer succeed. barebox MLO is entered, but hangs. Reset from within barebox is unaffected. This can be reproduced using DistroKit 949c5ef2b9a6 ("v7a: barebox: version bump v2021.08.0 → v2021.11.0") on a Beaglebone Black. Until that's figured out, revert the commit; functional reboot is more important than the quicker boot up. This reverts commit 130c7d6715e932a1e0b3e026fea97f700ab33ea9.
