2016-03-14dm: Add a new header for block devicesSimon Glass
At present block devices are tied up with partitions. But not all block devices have partitions within them. They are in fact separate concepts. Create a separate blk.h header file for block devices.

2016-03-14dm: Drop the block_dev_desc_t typedefSimon Glass
Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long and causes 80-column violations, rename it to struct blk_desc. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Stephen Warren <swarren@nvidia.com>
2016-01-14block: pass block dev not num to read/write/erase()Stephen Warren
This will allow the implementation to make use of data in the block_dev structure beyond the base device number. This will be useful so that eMMC block devices can encompass the HW partition ID rather than treating this out-of-band. Equally, the existence of the priv field is crying out for this patch to exist.

2014-07-22common: cmd_ide: use __weak and add prototypesJeroen Hofstee
clang chokes about the concept of having an alias to an always_inlined function. gcc likely just ignores the always inlined since binary sizes are equal before and after this patch. Convert the aliases to weak functions and provide missing prototypes. cc: Pavel Herrmann <morpheus.ibis@gmail.com> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

2013-07-24block: constify sect_buf argument of ide_write_dataGabor Juhos
Add a const keyword to the sect_buf argument of ide_write_data to fix the following warning: cmd_ide.c: In function '__ide_output_data': cmd_ide.c:548: warning: passing argument 2 of 'ide_write_data' discards qualifiers from pointer target type /devel/u-boot.git/include/ide.h:76: note: expected 'ulong *' but argument is of type 'const ulong *' Also modify the driver-model documentation to match with the new prototype.

2013-07-15Fix ext2/ext4 filesystem accesses beyond 2TiBFrederic Leroy
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 We now use lbaint_t for partition offset to reflect the lbaint_t change, and access partitions beyond or crossing the 2.1TiB limit. This required changes to signature of ext4fs_devread(), and type of all variables relatives to block sector. ext2/ext4 fs uses logical block represented by a 32 bit value. Logical block is a multiple of device block sector. To avoid overflow problem when calling ext4fs_devread(), we need to cast the sector parameter. Signed-off-by: Frédéric Leroy <fredo@starox.org>
2013-06-26Fix block device accesses beyond 2TiBSascha Silbe
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>

2012-10-17change all versions of input_data() and output_data() to global weak aliasesPavel Herrmann
This changes input_data() and friends from static function to global symbols under weak alias, to enable board specific overrides (and therefore get rid of board-specific code in cmd_ide.c) Also declare ide_bus_offset in the header file, so other files can use ATA_CURR_BASE as well.

2012-10-17split mpc8xx hooks from cmd_ide.cPavel Herrmann
move most of mpc8xx hooks from cmd_ide.c into ide_preinit() and newly created ide_init_postreset() (invoked after calling ide_reset after ide_preinit), some cleanup to make checkpatch happy, enable IDE init hooks in configs of affected boards. confusingly, these hooks are used by more than just mpc8xx-based boards, and therefore are placed in arch/ppc/lib/ note: checkpatch still emits warnings about using volatile Signed-off-by: Pavel Herrmann <morpheus.ibis@gmail.com>

2012-10-08ide: Correct IDE_BUS(dev) macroLuka Perkov
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.

2011-04-30cmd_ide: enhance new feature "CONFIG_IDE_AHB"Macpaul Lin
Although most IDE controller is designed to be connected to PCI bridge, there are still some IDE controller support AHB interface for SoC design. The driver implementation of these IDE-AHB controllers differ from other IDE-PCI controller, some additional registers and commands access is required during CMD/DATA I/O. 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.

2009-09-24mucmc52, uc101: delete ata@3a00 node, if no CF card is detectedHeiko Schocher
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>
