2019-12-02Move strtomhz() to vsprintf.hSimon Glass
At present this function sits in its own file but it does not really justify it. There are similar string functions in vsprintf.h, so move it there. Also add the missing function comment. Use the vsprintf.h include file explicitly where needed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

2018-09-10ARM: CPU: arm926ejs: Consolidate cache routines to common fileAdam Ford
Four different boards had different options for enabling cache that were virtually all the same. This consolidates these common functions into arch/arm/cpu/arm926ejs/cache.c This also has the positive side-effect of enabling cache on the Davinci (da850) boards.

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>

2017-05-31mx25: Fix imx_get_perclk()Benoît Thébaudeau
imx_get_perclk() used the AHB clock as the clock source for all PER clocks, but the USB PLL output can also be a PER clock source if the corresponding PER CLK MUX bit is set in CCM.MCR. Signed-off-by: Benoît Thébaudeau <benoit@wsystem.com> Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com>

2012-10-15mx25: Fix eSDHC supportBenoît Thébaudeau
The MMC driver appropriate for the i.MX25 is fsl_esdhc, which has nothing to do with mxcmmc. Also, each eSDHC instance has a dedicated clock, so gd->sdhc_clk must be set accordingly. This is good for the case only a single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A future patch will fix the multi-instance use case (initialization made directly with fsl_esdhc_initialize()).
