U-Boot doesn't honor the load address specified in an initrd. Barebox
shouldn't be more strict here. This unbreaks booting an uInitrd
generated by Debian's flash-kernel that uses 0 as entry address where
there is nothing on the i.MX53 that was used.

if (initrd is provided as uInitrd && data.initrd_address == UIMAGE_SOME_ADDRESS)
data.initrd_address = load_address_from_uInitrd;
...
if (data.initrd_address == UIMAGE_SOME_ADDRESS)
data.initrd_address = UIMAGE_INVALID_ADDRESS;
can be simplified to:
data.initrd_address = UIMAGE_INVALID_ADDRESS;
...
if (-L was given to bootm)
data.initrd_address = address_provided_to_-L;
...
if (initrd is provided as uInitrd && data.initrd_address == UIMAGE_INVALID_ADDRESS)
data.initrd_address = load_address_from_uInitrd;
...
The only change introduced by this simplification is for cases where the
user passes -L UIMAGE_SOME_ADDRESS or -L UIMAGE_INVALID_ADDRESS to
bootm. (-L UIMAGE_SOME_ADDRESS is now used literally instead of ignored
before. -L UIMAGE_INVALID_ADDRESS used to skip getting the
initrd-address from the uInitrd, now the uInitrd address is honored.)

Linux expects linux,initrd-end to contain the first unused address. As
this doesn't match the end semantic used by barebox (i.e. end contains
the last used address) adding one is necessary.
Without this change Linux fails for me to correctly extract a gzipped
cpio archive provided as initrd.

Since commit:
2ccd451 ARM i.MX28: change default watchdog reset method
the external reset via the reset pin is broken. That commit overwrites the
HW_CLKCTRL_RESET register with only WDOG_POR_DISABLE set, which results in
disabling the external reset.
This patch uses read-modify-write to set the WDOG_POR_DISABLE, leaving the
WDOG_POR_DISABLE untouched.

This switches the iomux-v3 (found on i.MX25,35,51,53,6) to pinctrl
support. The old SoC specific API is kept for compatibility. The
pinctrl devicetree support is enabled automatically when OFDEVICE
support is available.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
This is a massively stripped down pinctrl support. The upper API
consists of only of:
int pinctrl_select_state(struct device_d *dev, const char *state);
This is used to setup the pinmux for a device to a certain state.
This function normally does not need to be called manually. The
device core will setup the default state before probing a device.
The pinctrl core has the job of handling the devicetree. It parses
the pinctrl phandles for a device from devicetree, finds the correct
pinctrl device and calls its set_state callback with the pinctrl
setup device node.
The simplicity of this pinctrl framework comes from the fact that
we:
- Limit usage to devicetree only for now. For non devicetree use the
old legacy SoC specific APIs still can be used.
- Do not parse the devicetree into internal data structures which
are used by the drivers later. This adds the overhead that we
may parse the devicetree multiple times for more dynamic setups,
but on the other hand we do not need to parse devices from the
devicetree we don't use in barebox
- Do not detect resource conflicts. Since the framework mainly is
a devicetree parser this would be hard to implement. It should
be easy for board maintainers to avoid resource conflicts though.
