Re: [U-Boot] [PATCH 2/7] OMAP3: Beagle: Add board revision detection

/******************************************************************************

• • Routine: board_identify
• • Description: Detect if we are running on a Beagle revision Ax/Bx or

• •          Cx. This can be done by GPIO_171. If this is low, we are
    

• •          running on a revision C board.
    

• *****************************************************************************/

+void board_identify(void) +{

• gpio_t *gpio6_base = (gpio_t *)OMAP34XX_GPIO6_BASE;
• /* Configure GPIO 171 as input */

we may need to start to think about merge to the gpiolib to simplify it

• writel(readl(&gpio6_base->oe) | GPIO11, &gpio6_base->oe);
• /* Get value of GPIO 171 */
• beagle_revision_c = readl(&gpio6_base->datain) & BOARD_REVISION_MASK;
• printf("Board revision ");
• if (beagle_revision_c) {

??? I'm not a fan of glabal var please create a function that will return if it's a rev c or not
