Synchronise device tree with linux-next 20220706. Please note that this also means that instead of the previous "generic" U-Boot specific carrier board agnostic device tree we are now using the regular one for the Apalis Evaluation (carrier) board (e.g. imx6q-apalis-eval.dtb rather than the previous imx6-apalis.dtb).

2022-06-28board: apalis_imx6: DDR init using mx6_dram_cfg()Francesco Dolcini1-255/+187
Do DDR initialization using the procedural mx6_dram_cfg() instead of programming the MMDC using a raw list of register/value pairs, this solves some rare boot failures on specific "bad" modules. Calibration values, DDR geometry are unchanged, memory timings are updated according to the relevant memory datasheet, no changes on the power consumption. For IT temperature range SKUs CL is decreased from 8 to 7 and tFAW value is increased, for commercial temperature range SKUs some changes on ODT parameters. This change was validated over a range of different apalis-imx6 SoM, on the whole working temperature range with weeks of continuous testing.

2022-06-28toradex: apalis/colibri_imx6: Fix CLKO1/CLKO2 outputFrancesco Dolcini1-5/+9
Set CLK01 and CLK02 to 24MHz and enable it in CCM_CCOSR register. This clock is used by both the audio codec (CLKO1) and by the CSI camera (CLKO2) and is expected to be 24MHz. Despite the wrong 16.5MHz there was no real issue because of the wrong frequency since Linux reconfigures the clocks afterward, however this was triggering an issue with noise coming from the SGTL5000 audio codec. The problem is that the SGTL5000 does not have a reset pin and after it is configured if the input MCLK clock is disabled it produces a constant noise on its output, this was happening on software reboot. Forcing the clock to be enabled in U-Boot prevent the problem by making sure that the clock is always available, without this change as soon as Linux was changing the clock tree (setting clk_out_sel=1 without setting clko2_en=1) the noise would start till the actual clock was enabled (clko2_en=1) during the SGTL5000 driver probe.

2021-09-07arm: Disable ATAGs supportTom Rini1-3/+2
With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and stemmy, disable ATAG support. A large number of platforms had enabled support but never supported a kernel so old as to require it. Further, some platforms are old enough to support both, but are well supported by devicetree booting, and have been for a number of years. This is because some of the ATAGs related functions have been re-used to provide the same kind of information, but for devicetree or just generally to inform the user. When needed still, rename these functions to get_board_revision() instead, to avoid conflicts. In other cases, these functions were simply unused, so drop them.

2021-03-02reset: Remove addr parameter from reset_cpu()Harald Seiler1-1/+1
Historically, the reset_cpu() function had an `addr` parameter which was meant to pass in an address of the reset vector location, where the CPU should reset to. This feature is no longer used anywhere in U-Boot as all reset_cpu() implementations now ignore the passed value. Generic code has been added which always calls reset_cpu() with `0` which means this feature can no longer be used easily anyway. Over time, many implementations seem to have "misunderstood" the existence of this parameter as a way to customize/parameterize the reset (e.g. COLD vs WARM resets). As this is not properly supported, the code will almost always not do what it is intended to (because all call-sites just call reset_cpu() with 0). To avoid confusion and to clean up the codebase from unused left-overs of the past, remove the `addr` parameter entirely. Code which intends to support different kinds of resets should be rewritten as a sysreset driver instead. This transformation was done with the following coccinelle patch: @@ expression argvalue; @@ - reset_cpu(argvalue) + reset_cpu() @@ identifier argname; type argtype; @@ - reset_cpu(argtype argname) + reset_cpu(void) { ... } Signed-off-by: Harald Seiler <hws@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>

2021-01-05dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()Simon Glass1-1/+1
The current macro is a misnomer since it does not declare a device directly. Instead, it declares driver_info record which U-Boot uses at runtime to create a device. The distinction seems somewhat minor most of the time, but is becomes quite confusing when we actually want to declare a device, with of-platdata. We are left trying to distinguish between a device which isn't actually device, and a device that is (perhaps an 'instance'?) It seems better to rename this macro to describe what it actually is. The macros is not widely used, since boards should use devicetree to declare devices. Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is declaring a new driver_info record, not a device. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada1-2/+2
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>

2020-05-01board: apalis_imx6: Add KSZ9131 phy skew settingsPhilippe Schenker1-16/+73
This patch adds skew register settings for KSZ9131. It checks first which phy is on the board and then applies the correct skew settings. Skew settings calculation for the KSZ9131: The i.MX6 SoC has an output skew tolerance of -100ps to 900ps. All PCB traces where routed exactly the same length so we can calculate the skew settings without taking the length into consideration. The traces are all length matched. RXC skew (PHY to MAC): - We use the 2ns DLL controlled delay on the PHY - We do not use the skew registers This results in the following values: RXC PHY fixed Delay 2000ps PHY Added Delay 0ps T_setup_R min 2.00ns T_setup_R typ 2.00ns T_setup_R max 2.00ns T_hold_R min 1.60ns T_hold_R typ 2.00ns T_hold_R max 2.40ns That means we are well within RGMII specs. TXC skew (MAC to PHY): - We use the 2ns DLL controlled delay on the PHY - We then subtract ~0.6ns with TXD[0:3] and TXC clock pad skew register in a resulting ~1.4ns delay. This results in the following values under consideration of the tolerances: TXC min TXC typ TXC max MAC min -100ps -100ps -100ps MAC max 900ps 900ps 900ps PHY fixed Delay 2000ps 2000ps 2000ps PHY added Delay -340ps -600ps -859ps T_setup_T min 1.56ns 1.30ns 1.04ns T_setup_T typ 2.06ns 1.80ns 1.54ns T_setup_T max 2.56ns 2.30ns 2.04ns T_hold_T min 1.04ns 1.30ns 1.56ns T_hold_T typ 1.94ns 2.20ns 2.46ns T_hold_T max 2.84ns 3.10ns 3.36ns This shows that T_hold_T min and T_setup_T min times are out of spec for RGMII timing. However the KSZ9131 has a minimal value for this time of 0.8ns which is met under all circumstances. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>

We have two commands to change the bootmode fuses: mfgr_fuse which set fuse 0/5 and 0/6 and updt_fuse which burns bit 4 of 0/5. Before BSP 2.6 we fused in mfgr_fuse 0x5062, which boots from the user partition of the eMMC. To workaround certain hangs we moved to fastboot mode and using the first bootpartition of the eMMC requiring a fuse value of 0x5072 which could be achieved by the then added updt_fuse command. At the same time the mfgr_fuse command was changed to also fuse 0x5072, revert that second change so that one can fuse both values, one with just mfgr_fuse and the later with mfgr_fuse;updt_fuse. Note that the mfgr_fuse command is only needed at module production time, a customer might need to use updt_fuse when upgrading an older module to be compatible with a newer image.
