Add a multi-function device driver which will probe its children and provides methods to access the device. Signed-off-by: Michael Walle <michael@walle.cc> [Rebased] Signed-off-by: Priyanka Jain <priyanka.jain@nxp.com>
The watchdog timer is part of the sl28cpld management controller. The watchdog timer usually supervises the bootloader boot-up and if it bites the failsafe bootloader will be activated. Apart from that it supports the usual board level reset and one SMARC speciality: driving the WDT_TIMEOUT# signal.

The gpio block is part of the sl28cpld sl28cpld management controller. There are three different flavors: the usual input and output where the direction is configurable, but also input only and output only variants.

The current console output is: DRAM: 4 GiB DDR 4 GiB (DDR3, 32-bit, CL=11, ECC on) The size is printed twice and we can save one line of console output if we join both lines. The new output is as follows: DRAM: 4 GiB (DDR3, 32-bit, CL=11, ECC on) Signed-off-by: Michael Walle <michael@walle.cc> Reviewed-by: Priyanka Jain <priyanka.jain@nxp.com>
Most of the time it is very useful to have the version of the board management controller. Now that we have a driver, print it during startup. Signed-off-by: Michael Walle <michael@walle.cc> Reviewed-by: Priyanka Jain <priyanka.jain@nxp.com>
Enable the GPIO and watchdog driver. Don't start the watchdog automatically, though. Signed-off-by: Michael Walle <michael@walle.cc> Reviewed-by: Priyanka Jain <priyanka.jain@nxp.com>
The SoC provides two additional watchdogs integrated in the SoC. Enable support for these. Signed-off-by: Michael Walle <michael@walle.cc> Reviewed-by: Priyanka Jain <priyanka.jain@nxp.com>
This board has an internal watchdog which supervises the board startup. Although, the initial state of the watchdog is configurable, it is enabled by default. In board_late_init(), which means almost everything worked as expected, disable the watchdog. Signed-off-by: Michael Walle <michael@walle.cc> Reviewed-by: Priyanka Jain <priyanka.jain@nxp.com>
They are no longer needed, because we now have proper driver support for the sl28cpld management controller. Signed-off-by: Michael Walle <michael@walle.cc> Reviewed-by: Priyanka Jain <priyanka.jain@nxp.com>
Nowadays, u-boot (when CONFIG_NET_RANDOM_ETHADDR is set) will set
enetaddr to a random value if not set and then pass the randomly
generated MAC address to linux.
This is bad for the following reasons:
(1) it makes it impossible for linux to detect this error
(2) linux won't trigger any fallback mechanism for the case where
it didn't find any valid MAC address
(3) a saveenv will store this randomly generated MAC address in the
environment
Probably, the user will also be unaware that something is wrong. He will
just get different MAC addresses on each reboot, asking himself why this
is the case.
As this board usually have a serial port, the user can just fix this by
setting the MAC address manually in the environment. Also disable the
netconsole just in case, because it cannot be guaranteed that it will
work in any case. After all, this was just a convenience option, because
the bootloader - right now - doesn't have the ability to read the MAC
address, which is stored in the OTP. But it is far more important to
have a clear view of whats wrong with a board and that means we can no
longer use this Kconfig option.

The BOOT_TARGET_DEVICES list for distro_bootcmd was hard-coded to assume that all boot devices are available/enabled in the configuration, thus ignoring the actual config settings. The config_distro_bootcmd.h header file specifically has compile-time checks to detect such problems. To allow disabling USB, SCSI, etc. in custom lx2160a board configs, make it depend on the config settings and use only the enabled features.

The Layerscape platforms have different RCW header value from FSL PowerPC platforms, the current image header verification callback is only working on PowerPC, it will fail on Layerscape, this patch is to fix this issue.
