Following changes was made:
- Add MDIO signal names
- Add missing ISB_IN2 name. Also correct ISB_nIN1. These two signals were used
together in older HW revisions. Later ISB_IN2 was removed. Software should
still be able to use both.
- Add missing CAN1 and UART line names
- Add missing ON1/2_CTRL line names
- fix CPU_* line names. The real signal names are without the CPU_ prefix, like

With SIGTRAP on perf events, we have encountered termination of
processes due to user space attempting to block delivery of SIGTRAP.
Consider this case:
<set up SIGTRAP on a perf event>
...
sigset_t s;
sigemptyset(&s);
sigaddset(&s, SIGTRAP | <and others>);
sigprocmask(SIG_BLOCK, &s, ...);
...
<perf event triggers>
When the perf event triggers, while SIGTRAP is blocked, force_sig_perf()
will force the signal, but revert back to the default handler, thus
terminating the task.
This makes sense for error conditions, but not so much for explicitly
requested monitoring. However, the expectation is still that signals
generated by perf events are synchronous, which will no longer be the
case if the signal is blocked and delivered later.
To give user space the ability to clearly distinguish synchronous from
asynchronous signals, introduce siginfo_t::si_perf_flags and
TRAP_PERF_FLAG_ASYNC (opted for flags in case more binary information is
required in future).
The resolution to the problem is then to (a) no longer force the signal
(avoiding the terminations), but (b) tell user space via si_perf_flags
if the signal was synchronous or not, so that such signals can be
handled differently (e.g. let user space decide to ignore or consider
the data imprecise).
The alternative of making the kernel ignore SIGTRAP on perf events if
the signal is blocked may work for some usecases, but likely causes
issues in others that then have to revert back to interception of
sigprocmask() (which we want to avoid). [ A concrete example: when using
breakpoint perf events to track data-flow, in a region of code where
signals are blocked, data-flow can no longer be tracked accurately.
When a relevant asynchronous signal is received after unblocking the
signal, the data-flow tracking logic needs to know its state is
imprecise. ]

This is the full series for converting OMAP1 to multiplatform, rebased
from my 2019 attempt to do the same thing. The soc tree contains simpler
patches to do the same for iop32x, ixp4xx, ep93xx and s3c24xx, which
means we are getting closer to completing this for all ARMv5 platforms
(I have patches for PXA, which is the last one remaining).
Janusz already tested the branch separately and did the missing work

Commit ef772f2ee3 ("ARM: OMAP: Fix CONFIG_DEBUG_LL") was supposed to fix
low level debugging, most possibly by early enabling UART clocks. The fix
actually introduced early reset of most bits of MOD_CONF_CTRL_0 register,
with the exception of UART1 and UART2 clock related bits which were set
high. However, UART1 clock bit can play different roles on different
OMAP1 variants. On OMAP1610 it enables the clock as intended, but on
OMAP1510 it switches the clock rate from 12 to 48 MHz. Even worth, for
UART2 the bit changes its clock rate also on OMAP1610. As a result, UART
rates set by a bootloader can be unintentionally changed early on kernel
boot and low level debugging broken, not fixed. Besides, reset of all
other bits was not justified.
Don't touch register bits not related to UART clocks. Also, don't touch
the bit of UART2 clock. Make sure UART1 and UART3 are enabled early on
relevant OMAP1610 machine types while preserving bootloader UART clock
rates on others.

In a multiplatform randconfig kernel, one can have

This leads to some build issues as the code is not
meant to deal with this configuration at the moment:
arch/arm/mach-omap1/io.c:86:20: error: unused function 'omap1_map_common_io' [-Werror,-Wunused-function]
arch/arm/mach-omap1/pm.h:113:2: error: "Power management for this processor not implemented yet" [-Werror,-W#warnings]
Use the same trick as on OMAP2 and guard the actual compilation
of platform code with another Makefile ifdef check based
on an option that depends on having at least one SoC enabled.
