ARM: OMAP1: select CONFIG_GENERIC_IRQ_CHIP
When GENERIC_IRQ_CHIP is disabled, OMAP1 kernels fail to link:

arm-linux-gnueabi-ld: arch/arm/mach-omap1/irq.o: in function `omap1_init_irq':
irq.c:(.init.text+0x1e8): undefined reference to `irq_alloc_generic_chip'
arm-linux-gnueabi-ld: irq.c:(.init.text+0x228): undefined reference to `irq_setup_generic_chip'
arm-linux-gnueabi-ld: irq.c:(.init.text+0x2a8): undefined reference to `irq_gc_set_wake'
arm-linux-gnueabi-ld: irq.c:(.init.text+0x2b0): undefined reference to `irq_gc_mask_set_bit'
arm-linux-gnueabi-ld: irq.c:(.init.text+0x2b4): undefined reference to `irq_gc_mask_clr_bit'

This has apparently been the case for many years, but I never caught it
in randconfig builds until now, as there are dozens of other drivers
that also 'select GENERIC_IRQ_CHIP' and statistically there is almost
always one of them enabled.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
