          This Toshiba board is based on the TX4938 processor. Say Y here to
          support this machine type

RBTX4938(rbhma4500) uses i8259 which is not converted to irq flow
handler yet.

I'm afraid there's some mistake in Kconfig -- RBTX4938 doesn't have 8259 compatible controller. And the backplane that has it isn't supported by the current code anyway.

WBR, Sergei
