From 30f0b40844e5add7ad879e2f5939ff498f72f3e6 Mon Sep 17 00:00:00 2001 From: eric miao Date: Wed, 29 Aug 2007 10:18:47 +0100 Subject: [ARM] 4559/1: pxa: make PXA_LAST_GPIO a run-time variable This definition produces processor specific code in generic function pxa_gpio_mode(), thus creating inconsistencies for support of pxa25x and pxa27x in a single zImage. As David Brownell suggests, make it a run-time variable and initialize at run-time according to the number of GPIOs on the processor. For now the initialization happens in pxa_init_irq_gpio(), since there is already a parameter for that, besides, this is and MUST be earlier than any subsequent calls to pxa_gpio_mode().
