Add a -a option to specify changes to the config before the build
commences. For example
buildman -a ~CONFIG_CMDLINE
disables CONFIG_CMDLINE before doing the build.
This makes it easier to try things out as well as to write tests without
creating a new board or manually manging the .config file.

At present the only straightforward way to write tests that need a
slightly different configuration is to create a new board with its own
configuration. This is cumbersome.
It would be useful if buildman could adjust the configuration of a build
on the fly. In preparation for this, add a utility library which can
modify a .config file according to various parameters passed to it.

Use the new IF_ENABLED_INT() feature to avoid needing our own inline

is only used when present. Update the 'expected' comment also.

At present if an optional Kconfig value needs to be used it must be
bracketed by #ifdef. For example, with this Kconfig setup:
config WIBBLE
bool "Support wibbles, the world needs more wibbles"
config WIBBLE_ADDR
hex "Address of the wibble"
depends on WIBBLE
then the following code must be used:
#ifdef CONFIG_WIBBLE
static void handle_wibble(void)
{
int val = CONFIG_WIBBLE_ADDR;
...
}
#endif
static void init_machine()
{
...
#ifdef CONFIG_WIBBLE
handle_wibble();
#endif
}
Add a new IF_ENABLED_INT() to help with this. So now it is possible to
write, without #ifdefs:
static void handle_wibble(void)
{
int val = IF_ENABLED_INT(CONFIG_WIBBLE, CONFIG_WIBBLE_ADDR);
...
}
static void init_machine()
{
...
if (IS_ENABLED(CONFIG_WIBBLE))
handle_wibble();
}
The value will be CONFIG_WIBBLE_ADDR if CONFIG_WIBBLE is defined and will
produce a build error if not.. This allows us to reduce the use of #ifdef
in the code, ensuring that the compiler still checks the code even if it
is not ultimately used for a particular build.
Add a CONFIG_IF_ENABLED_INT() version as well.
If an attempt is made to use a value that does not exist (i.e. when the
conditional is not enabled), an error about a non-existing function is
generated, e.g.:
common/bloblist.c:447: undefined reference to `invalid_use_of_IF_ENABLED_INT'

The config_enabled() macro currently uses 0 as the default value. Update
it to allow any value, so we can pass it something else, such as a
non-existent function, to produce a build error if it is not defined.
Also tidy up the code style for IS_ENABLED() and drop the unnecessary
brackets (the value is a simple 0 or 1).
Signed-off-by: Simon Glass <sjg@chromium.org>
At present the IS_ENABLED() macro has extra brackets, making it possible
to write:
if IS_ENABLED(CONFIG_XXX)

The PLL_CMNLC clocks are modelled as a child clock device of seirra. In the
