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 <[email protected]>

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 <[email protected]> Signed-off-by: Peng Fan <[email protected]>

2020-06-22ARM: imx: ddr: Fill in missing DDRC ZQCTLx on i.MX7Marek Vasut
The iMX7 defines further DDRC ZQCTLx registers, however those were thus far missing from the list of registers and not programmed. On systems with LPDDR2 or DDR3, those registers must be programmed with correct values, otherwise the DRAM may not work. However, existing systems which worked without programming these registers before are now setting those registers to 0, which is the default value, so no functional change there.

The iMX7D RM 9.2.4.9.3 Power removal flow Table 9-11. Re-enabling power explicitly says both the DDR controller and the PHY must be reset in the correct sequence. Currently the code only resets the controller. This leads to a misbehavior where the system brings the DRAM up after reboot, but the DRAM is unstable. Add the missing reset. The easiest way to trigger this is by triggering WDT without having the WDT assert WDOG_B signal, i.e. mw.w 0x30280000 0x25 .

2020-06-03efi_loader: allow compiling with clangHeinrich Schuchardt
On ARM systems gd is stored in register r9 or x18. When compiling with clang gd is defined as a macro calling function gd_ptr(). So we can not make assignments to gd. In the UEFI sub-system we need to save gd when leaving to UEFI binaries and have to restore gd when reentering U-Boot. Define a new function set_gd() for setting gd and use it in the UEFI sub-system.

2020-05-22usb: ehci-omap: Add Support for DM_USB and OF_CONTROLAdam Ford
The omap3.dtsi file shows the usbhshost node with two sub-nodes for ohci and ehci. This patch file creates the usbhshost, and pulls the portX-mode information. It then locates the EHCI sub-node, and initializes the EHCI controller with the info pulled from the usbhshost node. There is still more to do since there isn't an actual link between the 'phys' reference and the corresponding phy driver, and there is no nop-xceiv driver yet. In the meantime, the older style reference to CONFIG_OMAP_EHCI_PHYx_RESET_GPIO is still needed to pull the phy out of reset until the phy driver is completed and the phandle reference is made.

The original nandbcb tool was designed for imx6 only, when trying to leverage it to replace the kobs-ng tool, we found the design is not friendly for supporting all platforms. To support all iMX6/7/8 platforms and for easy further maintain, I reconstruct the structure of the tool. The main changes including: 1. Use platform_data to determine the logic branches rather than simply use SOC name. 2. More data structures as parameter for functions. 3. Global variables to define the FCB/DBBT/FW locations. 4. Implement the kobs-ng default 4 FCB/4 DBBT/2 FW layout. 5. Support Hamming coding/ 40bit BCH/ 62bit BCH coding FCB. 6. Dump and compare all written FCB/DBBT to verify data integrity.
