SPDX: Convert all of our single license tags to Linux Kernel style 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>

ide: Correct IDE_BUS(dev) macro The IDE_BUS(dev) macro was previously doing dev >> 1. This however is a mis-match of the usage in common/cmd_ide.c and would cause boards with multiple ports / devices to not correctly detect all devices.

block: pass block dev not num to read/write/erase() This will allow the implementation to make use of data in the block_dev structure beyond the base device number.

Fix block device accesses beyond 2TiB With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives. For some obscure reason, the current U-Boot code uses lbaint_t for the number of blocks to read (a rather optimistic estimation of how RAM sizes will evolve), but not for the starting address. Trying to access blocks beyond the 2TiB boundary will simply wrap around and read a block within the 0..2TiB range. We now use lbaint_t for block start addresses, too. This required changes to all block drivers as the signature of block_read(), block_write() and block_erase() in block_dev_desc_t changed. Signed-off-by: Sascha Silbe <t-uboot@infra-silbe.de>

mucmc52, uc101: delete ata@3a00 node, if no CF card is detected U-Boot can detect if an IDE device is present or not. If not, and this new config option is activated, U-Boot removes the ATA node from the DTS before booting Linux, so the Linux IDE driver does not probe the device and crash. This is needed for buggy hardware (uc101) where no pull down resistor is connected to the signal IDE5V_DD7. Signed-off-by: Heiko Schocher <hs@denx.de>

Hence a configuration "CONFIG_IDE_AHB" in cmd_ide.c is required to be defined to support these kinds of SoC controllers. Such as Faraday's FTIDE020 series and Global Unichip's UINF-0301.
