Certain GPIO devices have the capability to switch their GPIOs into
open-drain mode, that is, instead of actively driving the output
(Push-pull output), the pin is connected to the collector (for a NPN
transistor) or the drain (for a MOSFET) of a transistor, respectively.
The pin then either forms an open circuit or a connection to ground,
depending on the state of the transistor.
This patch adds functions to the GPIO uclass to switch GPIOs to
open-drain mode on devices that support it.

This patch adds a driver for the built-in GPIO controller of the MPC85XX
SoC (probably supporting other PowerQUICC III SoCs as well).
Each GPIO bank is identified by its own entry in the device tree, i.e.
gpio-controller@fc00 {
#gpio-cells = <2>;
compatible = "fsl,pq3-gpio";
reg = <0xfc00 0x100>
}
By default, each bank is assumed to have 32 GPIOs, but the ngpios
setting is honored, so the number of GPIOs for each bank in configurable
to match the actual GPIO count of the SoC (e.g. the 32/32/23 banks of
the P1022 SoC).
The usual functions of GPIO drivers (setting input/output mode and output
value setting) are supported.
The driver has been tested on MPC85XX, but it is likely that other
PowerQUICC III devices will work as well.

This reverts commit 56adbb3872.
Since commit 56adbb3872 ("image.h: Tighten up content using handy
CONFIG_IS_ENABLED() macro."), I found my boards fail to boot Linux
because the commit changed the logic of macros it touched. Now,
IMAGE_ENABLE_RAMDISK_HIGH and IMAGE_BOOT_GET_CMDLINE are 0 for all
the boards.
As you can see in include/linux/kconfig.h, CONFIG_IS_ENABLE() (and
IS_ENABLED() as well) can only take a macro that is either defined
as 1 or undefined. This is met for boolean options defined in
Kconfig. On the other hand, CONFIG_SYS_BOOT_RAMDISK_HIGH and
CONFIG_SYS_BOOT_GET_CMDLINE are defined without any value in
arch/*/include/asm/config.h . This kind of clean-up is welcome,
but the options should be moved to Kconfig beforehand.
Moreover, CONFIG_IS_ENABLED(SPL_CRC32_SUPPORT) looks weird.
It should be either CONFIG_IS_ENABLED(CRC32_SUPPORT) or
IS_ENABLED(CONFIG_SPL_CRC32_SUPPORT). But, I see no define for
CONFIG_SPL_CRC32_SUPPORT anywhere. Likewise for the other three.
The logic of IMAGE_OF_BOARD_SETUP and IMAGE_OF_SYSTEM_SETUP were
also changed for SPL. This can be a problem for boards defining
CONFIG_SPL_OF_LIBFDT. I guess it should have been changed to
IS_ENABLED(CONFIG_OF_BOARD_SETUP).
In the first place, if we replace the references in C code,
the macros IMAGE_* will go away.
if (IS_ENABLED(CONFIG_OF_BOARD_SETUP) {

The various cache maintenance routines perform a number of loops over
cache lines. Rather than duplicate the code for performing such loops,
abstract it out into a new cache_loop macro which performs an arbitrary
number of cache ops on a range of addresses. This reduces duplication in
the existing L1 cache maintenance code & will allow for not adding
further duplication when introducing L2 cache support.

Allow L1 Icache & L1 Dcache line size to be specified separately, since
there's no architectural mandate that they be the same. The

and it defaults to being enabled if none of the cache sizes are set by
the configuration (ie. sizes are all the default 0), and code is
adjusted to #ifdef on that rather than on the definition of the sizes
(which will always be defined even if 0).

Signed-off-by: Paul Burton <paul.burton@imgtec.com>
Use CPHYSADDR to implement the virt_to_phys function for converting from
a virtual to a physical address for MIPS32, much as is already done for
MIPS64. This allows for virt_to_phys to work regardless of whether the
address being translated is in kseg0 or kseg1, unlike the previous
subtraction based approach which only worked for addresses in kseg0.
This allows for drivers to provide an address to virt_to_phys without
needing to manually ensure that kseg1 addresses are converted to
equivalent kseg0 addresses first.
