2021-01-25sunxi: Add support for H616 SoCJernej Skrabec2-1/+12
H616 is very similar to H6 so most of the infrastructure can be reused. However, two big differences are that it doesn't have functional SRAM A2 which is usually used for TF-A and it doesn't have ARISC co-processor. It also needs bigger SPL size - 48 KiB.

2021-01-25sunxi: Add H616 DRAM supportJernej Skrabec5-0/+1164
Allwinner H616 supports many types of DRAM. Most notably it supports LPDDR4. However, all commercially available boards at this time use only DDR3, so this commit adds only DDR3 support. Controller and MBUS are very similar to H6 but PHY is completely unknown.

2021-01-25sunxi: support loading with SPL > 32KBAndre Przywara1-2/+16
H616 supports and needs bigger SPL than 32 KiB, mostly due to big DRAM driver and need for PMIC configuration, which pulls several drivers which are not needed otherwise. spl_mmc_get_uboot_raw_sector() will now compare pre-configured size with that, reported in SPL header. If size in header is bigger, it will use that value instead. In the process of function rework, also add missing function argument.

It turns out that in rare cases, current analytical approach to detect correct DRAM bus width and rank on H6 doesn't work. On some TV boxes with DDR3, incorrect DRAM configuration triggers write leveling error which immediately stops initialization process. Exact reason why this error appears isn't known. However, if correct configuration is used, initalization works without problem. In order to fix this issue, simply try another configuration when any kind of error appears during initialization, not just those related to rank and bus width.

2020-03-18sunxi: SPL SPI: Add SPI boot support for the Allwinner H6 SoCAndre Przywara2-10/+33
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: Introduce is_sun6i_gen_spi()Andre Przywara1-8/+14
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 Przywara1-41/+53
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.

2020-01-26sunxi: Automate loading from 128KB MMC offsetAndre Przywara1-0/+20
Since commit 067e0b9684d4 ("sunxi: Allow booting from 128KB SD/eMMC offset") we support having the SPL loaded from either the traditional 8KB SD card/eMMC offset, or from the alternative location at 128KB. However the sector to find the U-Boot image was still hard-coded at compile time, and had to be adjusted for one of the two choices. Since we can actually override the function to return the sector offset, we can just check the boot source byte there to select the proper offset based on from where the SPL was loaded. This allows the very same binary image to be loaded from either 128KB or 8KB, with the U-Boot proper image always being located just behind the SPL.

2019-04-10sunxi: Allow booting from 128KB SD/eMMC offsetAndre Przywara1-0/+2
On modern Allwinner SoCs (tested: H2+, A64, H5, H6) the BootROM can actually load the SPL also from sector 256 (128KB) of an SD card or eMMC chip. For more details, see [1]. In this case the boot source indicator (written at offset 0x28 of SRAM A1) has bit 4 set, so it's 0x10 for SD card and 0x12 for eMMC. Add those new values to the existing boot source check to allow booting the SPL from those "high" disk offsets as well. For this to work, the value of CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR needs to be adjusted, for instance to 0x140 (right after the high SPL). Doing this dynamically sounds desirable, but looks nasty to implement.

2019-04-10arm: sunxi: Allow per-platform DRAM ZQ configuration on sun8iPaul Kocialkowski1-1/+3
A few sun8i platforms define specific default DRAM ZQ values, but they are not taken in account because of MACH_SUN8I being used for the 123 default first. Replace MACH_SUN8I with the list of platforms that don't have specific DRAM ZQ values, to avoid overwriting the default for those that do.

2019-04-10sunxi: dram_sun8i: Fix A33 memory initializationMichael Trimarchi1-1/+1
While the exact problem is not known, based on discussion between Philipp Tomsich and André Przywara it is guessed that exit self-refresh timing is not set with correct value. There may be implicit enter or exit Self-Refresh anywhere as part of some training phase. In ZynqMP register guide [1], which is close to the various Allwinner DRAM controllers, tXSDLL is bits [14:8], while the non-DLL tXS is bits [6:0]: Self refresh exit delay. So it could be safely increased and it only affects the time after the self-refresh “exit”, which happens only after (re-)initialisation. There was no document for cpu in question so based on oscilloscope readings [2][3] and observed result by comparing allwinner architecture. So set it same as Allwinner H5 silicon. Before this patch, failure rate of was 7%. This was tested on A33 allwinner cpu, dual rank connection connected with two MT41K512M16HA-125:A memory model. Memory is configured as DDR3 1.5V And also this is tested in A33-OLinuXino dev board.
