* reset: Remove addr parameter from reset_cpu()Harald Seiler2021-03-021-1/+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>
* common: Drop asm/global_data.h from common headerSimon Glass2021-02-022-0/+2
| | | | | | | | | | | | Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-073-7/+3
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
* mx6memcal: enable SDP supportEric Nelson2018-02-041-1/+0
| | | | | | | | | | | | The initial implementation of mx6memcal reset the CPU after running the memory calibration procedure because the generic board has no information about which boot devices are available. Now that we have SDP support in SPL, use it to allow a full U-Boot to be uploaded (i.e. to use "mtest").

* mx6memcal: Fix the UART ports for mx6sabresd/auto boardsFabio Estevam2018-01-121-10/+2
| | | | | | | | | | | | | | | | | | | | mx6sabresd board uses the following pins for console: PAD_CSI0_DAT10__UART1_TX_DATA PAD_CSI0_DAT11__UART1_RX_DATA ,so put it in the same config option as wandboard. mx6sabreauto board uses the following pins for console: PAD_KEY_COL0__UART4_TX_DATA PAD_KEY_ROW0__UART4_RX_DATA So do not mention sabreauto board as part of the UART1_SD3_DAT6_7 option. The config option for sabreauto can be added later when needed. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com>
* mx6: Add board mx6memcal for use in validating DDREric Nelson2018-01-036-0/+792
This is a virtual "board" that uses configuration files and Kconfig to define the memory layout used by a real board during the board bring-up process. It generates an SPL image that can be loaded using imx_usb or SB_LOADER.exe. When run, it will generate a set of calibration constants for use in either or both a DCD configuration file for boards that use u-boot.imx or struct mx6_mmdc_calibration for boards that boot via SPL. In essence, it is a configurable, open-source variant of the Freescale ddr-stress tool. https://community.nxp.com/docs/DOC-105652 File mx6memcal_defconfig configures the board for use with mx6sabresd or mx6qsabreauto.
