https://gitlab.denx.de/u-boot/custodians/u-boot-arc This last minute pull-request is intended to fix some drivers when used on ARC boards. The problem was introduced by https://gitlab.denx.de/u-boot/u-boot/-/commit/07906b3dad157bd58411664bcc6a2a7976d5e0a9 What happened while doing one pretty simple improvement to make U-Boot port more flexible and portable (by switching accessors from assembly-written to plain C version) we implicitly added 2 problems: 1. Downgraded accessors from being volatile which signalled to the compiler that it's now possible to do all kinds of optimizations which may easily include merge of subsequent byte reads/writes into word operations. Which is OK for accessing mormal memory but breaks operation of peripherals if we access its memory-mapped regs in such a "creative" manner. 2. As a part of assembly-written implementation we had compiler barriers in form of the following construction 'asm volatile("" : : : "memory")', and we dropped it in C implemntation. This in its turn enabled compiler to mess with instruction ordering. Guess what it gives us in the end :) So with all that we had in some corner-cases veeery funny instruction flows generated. And in particular it broke DW SPI functionality when we were writing large amount of data. Funny enough our tests which were writing small amount of data still worked and only by the chance we caught that breakage and unrolled that quite interesting loop of unexpected problems. The road to hell is paved with good intentions. Amen :)

We add memory barriers for __raw_readX / __raw_writeX accessors same way as it is done for readX and writeX accessors as lots of U-boot driver uses __raw_readX / __raw_writeX instead of proper accessor with barrier.

2020-03-18sunxi: Move common defconfig options to KconfigAndre Przywara
Some config symbols are found in *almost* every _defconfig file for Allwinner boards, because those options are actually a platform choice, and not a per-board decision. Some of these options are older, some have recently been added. Move those options to be set for all Allwinner boards in their respective Kconfig files. The rationales are as follows: - NR_DRAM_BANKS: All Allwinner SoC map DRAM at one contiguous region of address space only, starting at 1 GB. So it's always one bank. - SPL_{DOS,EFI}_PARTITION: The Allwinner SPL does only support raw MMC accesses, we don't care about filesystems or partitions in there, so there is no need to define those symbols at all. - USE_PREBOOT: We start USB early when a keyboard is configured, using the preboot env variable, so we need to set this variable. - SYS_RELOC_GD_ENV_ADDR: We don't specify any ENV_ADDR, so need this symbol to be set (according to 8d8ee47e03e). - SYS_USB_EVENT_POLL_VIA_INT_QUEUE: According to commit eab9433aa55428, specifying this reduces the latency of the USB keyboard handling, so this was formerly enabled in config headers for all Allwinner boards.

2020-03-18sunxi: SPL SPI: Add SPI boot support for the Allwinner H6 SoCAndre Przywara
The Allwinner H6 SoC uses a quite different memory map, also changes the clocks quite a bit. This requires some changes to the SPL SPI routine, which hardcodes these values so far. Using the just introduced helper functions to determine base address and SPI controller generation, we can cover some of these differences easily. The clock setup is different, so requires some explicit code changes there (reset and clock gate in one register at a different address). Also we need to change the pinmux function to use a different set of pins that the H6 uses for SPI0. Eventually we can enable the H6 to use SPI booting in Kconfig.

2020-03-18sunxi: SPL SPI: Add SPI boot support for the Allwinner R40 SoCAndre Przywara
Now that we can easily select an SoC specific SPI0 base address, adding support for the Allwinner R40 is fairly trivial: We set the base address, add this SoC to the ones that use PC23 and enable it in Kconfig. This allows booting from SPI flash on R40 boards. Tested on a Bananapi M2 Berry with SPI flash connected to the header pins.

2020-03-18sunxi: SPL SPI: Introduce is_sun6i_gen_spi()Andre Przywara
So far we were using the CONFIG_SUNXI_GEN_SUN6I symbol to select between the two SPI controller generations used on Allwinner SoCs. This is a convenience symbol to roughly differentiate between "older" and "newer" generation of SoCs. The H6 SoCs is the newest SoC so far, but is sufficiently different to not define this symbol. However it is using a SPI controller compatible to the "new gen" SoCs. To prepare for H6 support, we replace the check for this single symbol with an explicit function, which can later be extended. For now we just return CONFIG_SUNXI_GEN_SUN6I in there, so this does not create a functional change.

2020-03-18sunxi: SPL SPI: Split off SPI0 base addressAndre Przywara
So far on all supported Allwinner SoCs we find the old generation SPI controller always at address 0x1c05000, and the new generation one at 0x1c68000. However the Allwinner R40 SoC has a new generation SPI at the old address, and the H6 uses a completely different address. So split off the base address from the respective SPI registers, by changing the #defines to just contain offsets. The base address is provided by a function, so it can easily be extended later when support for those SoCs materialises. This does not change the code size (since the toolchain is clever enough to optimise this properly), also does not bring any functional change at this point.
