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>
2018-03-30x86: mmc: Fix mapping of BAR memoryBernhard Messerklinger
Use dm_pci_map_bar function for BAR mapping. This has the advantage of clearing BAR flags and and only accepting mapped memory.

2017-06-27Revert "x86: Convert MMC to driver model"Bin Meng
This reverts commit ddb3ac3c716f56cead695444e65a7ba7b0946555. With MMC converted to driver model, SCSI driver is broken due to zero address access at (ops->read) in block_dread() function. The fix (SCSI driver converted to DM) is ready in u-boot-dm branch, but it is too late for this relese to get that in.

2017-01-23mmc: sdhci: Distinguish between base clock and maximum peripheral frequencyStefan Herbrechtsmeier
The sdhci controller assumes that the base clock frequency is fully supported by the peripheral and doesn't support hardware limitations. The Linux kernel distinguishes between base clock (max_clk) of the host controller and maximum frequency (f_max) of the card interface. Use the same differentiation and allow the platform to constrain the peripheral interface. Signed-off-by: Stefan Herbrechtsmeier <stefan.herbrechtsmeier@weidmueller.com>

2016-01-12dm: Convert PCI MMC over to use DM PCI APISimon Glass
At present pci_mmc_init() does not correctly use the PCI function since the list it passes is not terminated. The array size passed to pci_mmc_init() is actually not used correctly. Fix this and adjust the pci_mmc_init() to scan all available MMC devices. Adjust this code to use the new driver model PCI API. This should move over to the new MMC uclass at some point.

2015-02-06x86: mmc: Move common FSP functions into a common fileSimon Glass
Since these board functions seem to be the same for all boards which use FSP, move them into a common file. We can adjust this later if future FSPs need more flexibility.
