2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-05-18common: Drop net.h from common headerSimon Glass
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>

2020-04-27ARC: HSDK-4xD: make init status resistant to U-boot reloadingEugeniy Paltsev
Use register intstead of static variable to store HSDK init status as we want to avoid the situation when we reload U-boot via MDB after previous init is done but HW reset (board reset) isn't done. So let's store the init status in unused register - CREG_CPU_0_ENTRY so status will survive after U-boot is reloaded via MDB.

2020-04-27ARC: HSDK-4xD: tweak memory mapEugeniy Paltsev
For HSDK-4xD we do additional AXI bridge tweaking while doing hsdk_init command: - we shrink IOC region. - we configure ARC HS CORE SLV1 aperture depending on haps_apb_location environment variable.

2020-04-27ARC: HSDK-4xD: add CSM configuration supportEugeniy Paltsev
Add support for CSM enable/disable and CSM relocation via hsdk_init command. We allow to relocate CSM to the beginning of any aperture even if HW support finer granularity. Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

2020-04-27ARC: HSDK-4xD: drop additional GPU clock infoEugeniy Paltsev
HSDK-4xD has other GPU type so it consumes only GPU core clock. Even we have additional GPU clock dividers they are not routed to anything.

2020-04-27ARC: HSDK-4xD: use active low polarity of cpu_start pulseEugeniy Paltsev

2020-02-12ARC: rework setting of ARC CPU specific compiler optionsEugeniy Paltsev
It's a very rare if at all existing occasion when ARC CPU template is used as is w/o any changes - in the end it's a beauty and competitive advantage of ARC cores to be tailored for a particular use-case - and so it doesn't make a lot of sense to offer template-based "-mcpu" selection. Given for each and every platform we end-up adding quite a few more flags it's logical to move "-mcpu" selection to platform's definition as well which we exactly do here.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-12-02common: Move enable/disable_interrupts out of common.hSimon Glass

2019-12-02common: Move some cache and MMU functions out of common.hSimon Glass
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>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2018-04-02ARC: HSDK: Add platform-specific commandsEugeniy Paltsev
This patch add support of hsdk platform-specific commands: hsdk_clock set - set clock from axi_freq, cpu_freq and tun_freq environment variables/command line arguments hsdk_clock get - save clock frequencies to axi_freq, cpu_freq and tun_freq environment variables hsdk_clock print - show CPU, AXI, DDR and TUNNEL current clock frequencies. hsdk_clock print_all - show all currently used clock frequencies. hsdk_init - setup board HW in one of pre-defined configuration (hsdk_hs34 / hsdk_hs36 / hsdk_hs36_ccm / hsdk_hs38 / hsdk_hs38_ccm / hsdk_hs38x2 / hsdk_hs38x3 / hsdk_hs38x4) hsdk_go - run baremetal application on hsdk configured by hsdk_init command. This patch changes default behaviour of 'bootm' command: now we are able to set number of CPUs to be kicked by setting 'core_mask' environment variable before 'bootm' command run.

2017-12-11ARC: HSDK: Fixup DW SDIO CIU frequency to 50000000HzEugeniy Paltsev
DW SDIO controller has external CIU clock divider controlled via register in the SDIO IP. Due to its unexpected default value (we expected it to divide by 1 but in reality it divides by 8) SDIO IP uses wrong CIU clock (it should be 100000000Hz but actual is 12500000Hz) and works unstable (see STAR 9001204800). So increase SDIO CIU frequency from actual 12500000Hz to 50000000Hz by switching from the default divisor value (div-by-8) to the minimum possible value of the divisor (div-by-2) in HSDK platform code.
