[U-Boot] P1020RDB_NAND build issues

[Wolfgang Denk]

Dear Kumar,

the P1020RDB_NAND is not build clean. For local (in-tree) builds I
get:

Configuring for P1_P2_RDB board...
nand_boot.c: In function 'board_init_f':
nand_boot.c:44: warning: 'sys_clk' may be used uninitialized in this function


and for out-of-tree builds I get even this:

Configuring for P1_P2_RDB board...
make[1]: *** No rule to make target `/work/wd/tmp-ppc/nand_spl/board/freescale/p1_p2_rdb/.depend', needed by `all'.  Stop.
make: *** [nand_spl] Error 2
make: *** Waiting for unfinished jobs....
ppc_6xx-size: '/work/wd/tmp-ppc/u-boot': No such file


Please fix.

Best regards,

Wolfgang Denk
