ide: Move ide_init() into probing

At present the code does ide_init() as a separate operation, then calls
device_probe() to copy over the information. We can call ide_init() from
probe just as easily.

The only difference is that using 'ide init' twice will do nothing.
However it already fails to copy over the new data in that case, so the
effect is the same. For now, unbind the block devices and remove the IDE
device, which causes the bus to be probed again. Later patches will fix
this up fully, so that all blk_desc data is copied across.

Since ide_reset() is only called from ide_init(), there is no need to init
the ide_dev_desc[] array. This is already done at the end of ide_init() so
drop this code.

The call to uclass_first_device() is now within the probe() function of
the same device, so does nothing. Drop it.

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.

Fix ext2/ext4 filesystem 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

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.

For some obscure reason, the current U-Boot code uses lbaint_t for the

Fix ext2/ext4 filesystem 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

We now use lbaint_t for partition offset to reflect the lbaint_t change,

This required changes to signature of ext4fs_devread(), and type of all

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.

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.

ide: Add printf format string for CONFIG_SYS_64BIT_LBA option

The size of an LBA type changes depending on this option. We need to
use a different printf() string in each case, so create a define for
this.

change all versions of input_data() and output_data() to global weak aliases

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.

split mpc8xx hooks from cmd_ide.c

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

ide.h: Make ide_(read|write) match block_dev_desc_t block_(read|write)

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. For more
details please see:

IDE: fix compiler warnings

The changes introduced by commit 0abddf8 ``cmd_ide: enhance new
feature "CONFIG_IDE_AHB"'' caused compiler warnings like

cmd_ide.c: In function 'ide_init':
cmd_ide.c:716: warning: assignment from incompatible pointer type

Constify the respective function arguments to fix this.

cmd_ide: enhance new feature "CONFIG_IDE_AHB"

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.

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.

IDE: - make ide_inb () and ide_outb () "weak", so boards can
define there own I/O functions.
(Needed for the pcs440ep board).
- The default I/O Functions are again 8 Bit accesses.

[PATCH 9_9] Use "void *" not "unsigned long *" for block dev read_write buffer pointers

Block device read/write is anonymous data; there is no need to use a
