clk->id is unsigned, so it can't be < 0. Remove the check for that.

FWIW, this issue was introduced when the clock API converted e.g.
clk_get_rate()'s clock ID parameter from an int to an unsigned long
(with a struct clk), without removing this check.

When building a FIT with external data (-E), U-Boot proper may require
absolute positioning for executing the external firmware. To acheive this
use the (-p) switch, which will replace the amended 'data-offset' with

It is considered an error if the requested absolute position overlaps with the

There are some cases where config options are moved, but they are
ripped off at the final savedefconfig stage:

  - The moved option is not user-configurable, for example, due to
    a missing prompt in the Kconfig entry

  - The config was not defined in the original config header despite
    the Kconfig specifies it as non-bool type

  - The config define in the header contains reference to another
    macro, for example:
        #define CONFIG_CONS_INDEX     (CONFIG_SYS_LPC32XX_UART - 2)
    The current moveconfig does not support recursive macro expansion.

In these cases, the conversion is very likely to be an unexpected
result.  That is why I decided to display the log in yellow color
in commit 5da4f857 ("tools: moveconfig: report when CONFIGs are
removed by savedefconfig").

It would be nice to display the list of suspicious boards when the
tool finishes processing.  It is highly recommended to check the
defconfigs once again when this message is displayed.

The subprocess.Popen() does not change the child process's working
directory if cwd=None is given.  Let's exploit this fact to refactor
the source directory handling.

We no longer have to pass "-C <reference_src_dir>" to the sub-process
because self.current_src_dir tracks the source tree against which we
want to run defconfig/autoconf.

The flag self.use_git_ref is not necessary either because we can know
the current state by checking whether the self.current_src_dir is a
valid string or None.

This patch adds a phy driver for the Micrel KSZ886x switches.

Similarly to the KSZ8895, SoC MAC is directly connected to the switch
MAC on the switch CPU port, so the link to the switch is always up.

KSZ886x switches can be used in the following configuration modes:
- Unmanaged mode with config stored in external EEPROM
- Managed mode over SPI
- Managed mode over I2C
- Managed mode over mdio/mdc (aka MIIM or SMI)

This patch supports only unmanaged and MIIM modes.

Based on Micrel KSZ886x driver from Linux kernel and
Micrel KSZ8895 driver from U-Boot.

Verified with the KSZ8863MLL.

The rtl8169 driver uses a global variable to store the register address
of the adapter being operated upon. This is updated to point at the
correct adapter when sending or receiving a packet, or shutting down the
adapter, but not when initializing the adapter. Consequently, switching
between different adapters within the same U-Boot runtime does not work
correctly since the driver programs the wrong registers during
rtl8169_eth_start() -> rtl8169_common_start() -> rtl8169_hw_start().

Note that since rtl8169_eth_stop() does set the global variable, the
second consecutive attempt to use the "new" adapter did work even before
this patch, because each time network usage is shut down, the network
core calls stop, which sets the variable so that the next start does
actually initialize the hardware, and the adapter works.

Equally, rtl8169_eth_probe() calls rtl_init() which sets the global, so
if using only a single device, or if picking the "right" device (based on
probe order) when multiple devices are present, ioaddr will already be set
correctly from the get-go, so the issue does not occur.

DISTRO_DEFAULTS is intended to mirror / replace
include/config_distro_defaults.h.

The intend is for boards which include this file to select this from
their Kconfig files and when moving setting to Kconfig which are #define-ed
in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that
boards which have selected DISTRO_DEFAULTS will keep the same configuration
as before without needing any defconfig file changes.

The initial list of selected things matches all settings recently removed
from config_distro_defaults.h because they have been converted to Kconfig,
with the exception of CMD_ELF and CMD_NET, which have a default of y, if
the default of these ever changes they should be selected by DISTRO_DEFAULTS
too.

For testing and example purposes this commit also converts ARCH_SUNXI
to use DISTRO_DEFAULT instead of selecting everything it needs itself.

The PSCI implementation expects at most 2 pages worth of space reserved
at the end of the secure section for its stacks. If PSCI is relocated to
secure SRAM, then everything is fine. If no secure SRAM is available,
and PSCI remains in main memory, the reserved memory space doesn't cover
the space used by the stack.

If one accesses PSCI after Linux has fully booted, the memory that should
have been reserved for the PSCI stacks may have been used by the kernel
or userspace, and would be corrupted. Observed after effects include the
system hanging or telinit core dumping when trying to reboot. It seems
the init process gets hit the most on my test bed.

This fix allocates the space used by the PSCI stacks in the secure
section by skipping pages in the linker script, but only when there is
no secure SRAM, to avoid bloating the binary.

This fix is only a stop gap. It would be better to rework the stack
allocation mechanism, maybe with proper usage of CONFIG_ macros and an
explicit symbol.
