What is a patch to fix this? I've got some errors after update to latest master tree: Board: ConnectCore i.MX51 detected i.MX51 revision 3.0 mmu: Error: Can't request SDRAM region for ttb Error: Cannot request SDRAM region for stack Module Variant: i.MX515@600MHz, PHY, Accel (0x0b) Module HW Rev : 03 Module Serial : B111156789 mc13xxx-spi mc13xxx-spi0: Found MC13892 ID: 0x0045d0 [Rev: 2.0a] nand: ONFI flash detected ... nand: ONFI param page 0 valid nand: Manufacturer ID: 0x2c, Chip ID: 0xda (Micron MT29F2G08AAD), page size: 2048, OOB size: 64 BUG: failure at arch/arm/cpu/mmu.c:122/find_pte()!
