This mxs_dma_desc_alloc() is called in a loop in the MXS NAND driver, this is even worse ;-) Possibly some common mx28 init code would be better? NAK (sorry, I know it hurts) Best regards, Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
