2020-07-14drivers: ddr: imx8mp: Add inline ECC feature supportSherry Sun
the DRAM Controller in i.MX8MP will support a feature called "Inline ECC". This is supported for all 3 supported DRAM technologies (LPDDR4, DDR4 and DDR3L). When this feature is enabled by software, the DRAM Controller reserves 12.5% of DRAM capacity for ECC information, and presents only the non-ECC portion (lower 87.5% of the installed capacity of DRAM) to the rest of the SoC. The DRAM memory can be divided into 8 regions so that if a use case only requires ECC protection on a subset of memory, then only that subset of memory need support inline ECC. If this occurs, then there is no performance penalty accessing the non-ECC-protected memory (no need to access ECC for this portion of the memory map). This is all configured with the DRAM Controller. Signed-off-by: Sherry Sun <sherry.sun@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>

2020-07-11ARM: uniphier: remove NAND reset codeMasahiro Yamada
Now that commit 3e57f879eee6 ("mtd: nand: raw: denali: Assert reset before deassert") added the reset assertion, this code in the board file is unneeded. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Always put the controller in reset, then take it out of reset. This is to make sure controller always in reset state in both SPL and proper Uboot.

This UART controller is integrated with a FIFO. Enable it. You can put the next character into the FIFO while the transmitter is sending out the current character. This works slightly faster. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-07-11serial: uniphier: flush transmitter before changing hardware settingsMasahiro Yamada
Ensure the transmitter is empty when chaining the baudrate or any hardware settings. If a character is remaining in the transmitter, the console will be garbled. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-07-11serial: uniphier: use register macros instead of structureMasahiro Yamada
After all, I am not a big fan of using a structure to represent the hardware register map. You do not need to know the entire register map. Add only necessary register macros. Use FIELD_PREP() instead of maintaining a pair of shift and mask. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2020-07-11bus: uniphier-system-bus: add UniPhier System Bus driverMasahiro Yamada
Since commit 1517126fdac2 ("ARM: uniphier: select DM_ETH"), DM-based drivers/net/smc911x.c is compiled, but it is never probed because the parent node lacks the DM-based driver. I need a skeleton driver to populate child devices (but the next commit will move more hardware settings to the this driver). I put this to drivers/bus/uniphier-system-bus.c because this is the same path as the driver in Linux kernel. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2020-07-11ARM: uniphier: consolidate SoC select menuMasahiro Yamada
Currently, the supports for the following two ARMv7 SoC groups are exclusive, because the boot ROM loads the SPL to a different address: - LD4, sLD8 (SPL is loaded at 0x00040000) - Pro4, Pro5, PXs2, LD6b (SPL is loaded at 0x00100000) This limitation exists only when CONFIG_SPL=y. Instead of using crappy CONFIG options, checking SPL and SPL_TEXT_BASE is cleaner. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-07-11ARM: uniphier: increase CONFIG_SYS_MONITOR_LEN to 2MBMasahiro Yamada
I increased the maximum U-Boot proper size from time to time, but configs/uniphier_v7_defconfig hit the current limit 832KB. Some historical info: In the initial support, the max size was 512MB. Commit 58d702274c09 ("ARM: uniphier: increase CONFIG_SYS_MONITOR_LEN") increased it to 576KB, and commit 3ce5b1a8d86d ("ARM: uniphier: move SPL stack address") moved the SPL stack location to avoid the memory map conflict. It was the solution to increase the size without changing the NOR boot image map. commit 1a4bd3a095b2 ("ARM: uniphier: increase CONFIG_SYS_MONITOR_LEN again") ended up with increasing the max size again, breaking the NOR boot image map. The limit was set to 832KB, otherwise the SPL stack would overwrite the U-Boot proper image: CONFIG_SPL_STACK - CONFIG_SYS_UBOOT_BASE + sizeof(struct image_header) = 0xd0000 To increase CONFIG_SYS_MONITOR_LEN even more, the SPL stack must be moved somewhere. I put it back to the original location prior to commit 3ce5b1a8d86d. With this change, there is no more practical size limit. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-07-11Revert "ARM: uniphier: add weird workaround code for LD20"Masahiro Yamada
This reverts commit 45f41c134baf5ff1bbf59d33027f6c79884fa4d9. This weird workaround was the best I came up with at that time to boot U-Boot from TF-A. I noticed U-Boot successfully boots on LD20 (i.e. CA72 CPU) by using the latest TF-A. Specifically, since the following TF-A commit, U-Boot runs at EL2 instead of EL1, and this issue went away as a side-effect. |commit f998a052fd94ea082833109f25b94ed5bfa24e8b |Author: Masahiro Yamada <yamada.masahiro@socionext.com> |Date: Thu Jul 25 10:57:38 2019 +0900 | | uniphier: run BL33 at EL2 | | All the SoCs in 64-bit UniPhier SoC family support EL2. | | Just hard-code MODE_EL2 instead of using el_implemented() helper. | | Change-Id: I7ab48002c5205bc8c013e1b46313b57d6c431db0 | Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> However, if I reverted that, this problem would come back, presumably because some EL1 code in U-Boot triggers this issue. Now that commit f8ddd8cbb513 ("arm64: issue ISB after updating system registers") fixed this issue properly, this weird workaround is no longer needed irrespective of the exception level at which U-Boot runs.

2020-07-10config: Enable support for the XHCI controller on RPI4 boardMarek Szyprowski
This requires enabling BRCMSTB PCIe and XHCI_PCI drivers as well as PCI and USB commands. To get it working one has to call the following commands: "pci enum; usb start;", thus such commands have been added to the default "preboot" environment variable. One has to update their environment if it is already configured to get this feature working out of the box. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>
