2020-10-22sunxi: make V3s DRAM initialization more properIcenowy Zheng
Previously, because we have no source code about the DRAM initialization of V3s and missing some configurations (delays and MBUS QoS info), our V3s DRAM initialization sequence is hacked from the H3 one. As the SDK shipped with PineCube contains source code for V3s libdram, we can retrieve these information from it and tweak some other magic bits.

2020-10-05phy: meson-gxl: remove invalid USB3 PHY driverNeil Armstrong
The registers which are managed by the meson-gxl-usb3 PHY driver are actually "USB control" registers (which are "glue" registers which manage OTG detection and routing of the OTG capable port between the DWC2 peripheral-only controller and the DWC3 host-only controller). Drop the meson-gxl-usb3 PHY driver now that the dwc3-meson-gxl-usb driver supports the USB control registers on GXL and GXM SoCs (these were previously managed by the meson-gxl-usb3 PHY driver).

2020-10-05usb: dwc3: add Amlogic GXL & GXL DWC3 GlueNeil Armstrong
The USB support was initialy done with a set of PHYs and dwc3-of-simple because the architecture of the USB complex was not understood correctly at the time (and proper documentation was missing...). But with the G12A family, the USB complex was correctly understood and implemented correctly. This adds a proper driver for the glue, based on the G12A one, but with enough changes to require a different driver in U-Boot. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

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>
