2020-04-27ARM: zynq: Fix invalid check on NAND_CMD_NONE.Patrick van Gelder
The end_cmd field in the variables cmd_phase_addr and data_phase_addr contains the value 0xFF when the end_cmd equals NAND_CMD_NONE. This should be 0x00. This is caused by comparing NAND_CMD_NONE (int) with end_cmd (u8). end_cmd will be promoted by the int value -1 and therefore is not equal to 0xFF. Solved by casting NAND_CMD_NONE to u8 which will avoid int promotion.

2020-04-27ARM: zynq: Change SYS_MALLOC_LEN in zynq_cse_nand_defconfigT Karthik Reddy
nand_scan_tail() function allocates memory dynamically for struct nand_buffers which needs ~21kbytes of memory. But the memory alloted with CONFIG_SYS_MALLOC_LEN is 4k which is insufficient. Increase CONFIG_SYS_MALLOC_LEN to 32Kbytes from which struct nand_buffers uses ~21kbytes & remaining memory is used for other.
