* global: Move remaining CONFIG_SYS_NS16550_* to CFG_SYS_NS16550_*Tom Rini2022-12-051-2/+2
| | | | | | | | | | The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_NS16550 namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace.

* 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>

| | | | | | | | | | | Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
* common: Move some cache and MMU functions out of common.hSimon Glass2019-12-021-0/+1
| | | | | | | | | | | | These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | 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>

The patch is also backward compatible with old revision EVM and EVM with WireBond SoC. Their ARM/DDR3 run at 600MHz/800 MT/s. The new SoC supports 2 different speeds at 1GHz and 600MHz. Modyfied the CPU Name to show which SoC is used in the EVM. Modified the DDR3 configuration to reflect New SoC supports 2 different CPU and DDR3 speeds, 1GHz/1066MT and 600MHz/800MT. Added new inline function board_it_k2g_g1() for the new FlipChip 1GHz, and set the u-boot env variable board_name accordingly.

* ARM: keystone2: Refactor MSMC macros to avoid #ifdefferyNishanth Menon2016-04-011-7/+36
| | | | | | | | | | | | | | | MSMC segment Privilege ID is not consistent accross the keystone2 SoCs. As the first step to ensure complete SoC wide coherency setup, lets refactor the macros to remove the #if-deffery around the code which obfuscates which IDs are actually enabled for which SoC. As a result of this change the PCIe configuration is moved after the msmc configuration is complete, but that should ideally have no functional impact.
