linux/kconfig.h: create two- and three-argument versions of CONFIG_IS_ENABLED

CONFIG_IS_ENABLED. The existing semantics of
CONFIG_IS_ENABLED(FOO)
expanding to a 1 or 0 (depending on build context and the defined-ness
or not of the appropriate CONFIG_FOO/CONFIG_SPL_FOO/CONFIG_TPL_FOO)

CONFIG_IS_ENABLED(FOO, (something))

expand to 1, and expands to nothing otherwise. It is, in other words,
completely equivalent to the three lines
#if CONFIG_IS_ENABLED(FOO)
something
#endif
The second argument must be parenthesized in order to allow any
tokens, including a trailing comma, to appear - one use case for this
is precisely to make it a bit more ergonomic to build an array and
only include certain items depending on .config. That should increase
both readability and not least "git grep"ability.

This is fine if the framebuffer is allocated in fixed memory, as it

test: dm: rtc: add test of dm_rtc_read, dm_rtc_write
Define a few aux registers and check that they can be read/written
individually. Also check that one can access the time-keeping
registers directly and get the expected results.
The problem is that after each register write,
sandbox_i2c_rtc_complete_write() gets called and sets the internal
time from the current set of registers. However, when we get to
writing 31 to mday, the registers are in an inconsistent state (mon is
still 4), so the mktime machinery ends up translating April 31st to
May 1st. Upon the next register write, the registers are populated by
sandbox_i2c_rtc_prepare_read(), so the 31 we just wrote to mday gets
overwritten by a 1.
Fix it by writing all registers at once, and for consistency, update
the get method to retrieve them all with one "i2c transfer".
Mostly as an aid for debugging RTC drivers, provide a command that can
be used to read/write arbitrary registers (assuming the driver
provides the read/write methods or their single-register-at-a-time
variants).
This simply consists of renaming the existing pcf2127_read_reg()
helper to follow the naming of the other
methods (i.e. pcf2127_rtc_<method name>) and changing the type of its
"len" parameter.
rtc: fall back to ->{read, write} if ->{read, write}8 are not provided
Similar to how the dm_rtc_{read,write} functions fall back to using
the {read,write}8 methods, do the opposite in the rtc_{read,write}8
functions.
This way, each driver only needs to provide either ->read8 or ->read
to make both rtc_read8() and dm_rtc_read() work - without this, a
driver that provides ->read() would most likely just duplicate the
logic here for implementing a ->read8() method in term of its ->read()
method. The same remarks of course apply to the write case.
Similar to dm_rtc_read(), introduce a helper that allows the caller to
write multiple consecutive 8-bit registers with one call. If the
driver provides the ->write method, use that, otherwise loop using
->write8.
Some users may want to read multiple consecutive 8-bit
registers. Instead of each caller having to implement the loop,
provide a dm_rtc_read() helper. Also, allow a driver to provide a
->read method, which can be more efficient than reading one register
at a time.

spl: fit: select SPL_CRYPTO_SUPPORT for SPL_FIT_SIGNATURE
Verifying FIT images obviously needs the rsa parts of crypto
support and while main uboot always compiles crypto support,
it's optional for SPL and we should thus select the necessary
option to not end up in compile errors like:
u-boot/lib/rsa/rsa-verify.c:328: undefined reference to `rsa_mod_exp'
So select SPL_CRYPTO_SUPPORT in SPL_FIT_SIGNATURE.

spl: fit: select SPL_HASH_SUPPORT for SPL_FIT_SIGNATURE
rsa-checsum needs support for hash functions or else will run into
compile errors like:
u-boot/lib/rsa/rsa-checksum.c:28: undefined reference to `hash_progressive_lookup_algo'
So similar to the main FIT_SIGNATURE entry selects HASH,
select SPL_HASH_SUPPORT for SPL_FIT_SIGNATURE.

lib: rsa: add documentation to padding_pss_verify to document limitations
padding_pss_verify only works with the default pss salt setting of -2
(length to be automatically determined based on the PSS block structure)
not -1 (salt length set to the maximum permissible value), which makes
verifications of signatures with that saltlen fail.
Until this gets implemented at least document this behaviour.

lib: rsa: free local arrays after use in rsa_gen_key_prop()
n, rr and rrtmp are used for internal calculations, but in the end
the results are copied into separately allocated elements of the
actual key_prop, so the n, rr and rrtmp elements are not used anymore
when returning from the function and should of course be freed.

lib: rsa: fix allocated size for rr and rrtmp in rsa_gen_key_prop()
When calculating rrtmp/rr rsa_gen_key_prop() tries to make
(((rlen + 31) >> 5) + 1) steps in the rr uint32_t array and
(((rlen + 7) >> 3) + 1) / 4 steps in uint32_t rrtmp[]
with rlen being num_bits * 2
On a 4096bit key this comes down to to 257 uint32_t elements
in rr and 256 elements in rrtmp but with the current allocation
rr and rrtmp only have 129 uint32_t elements.
On 2048bit keys this works by chance as the defined max_rsa_size=4096
allocates a suitable number of elements, but with an actual 4096bit key
this results in other memory parts getting overwritten.
So as suggested by Heinrich Schuchardt just use the actual bit-size
of the key as base for the size calculation, in turn making the code
compatible to any future keysizes.
