MSM7x30 isn't supported in this driver yet. If ones tried to compile it in with MSM7x30 configure you get, linux-2.6/drivers/mmc/host/msm_sdcc.c: In function 'msmsdcc_fifo_addr': linux-2.6/drivers/mmc/host/msm_sdcc.c:165: error: 'MSM_SDC1_PHYS' undeclared (first use in this function) linux-2.6/drivers/mmc/host/msm_sdcc.c:165: error: (Each undeclared identifier is reported only once linux-2.6/drivers/mmc/host/msm_sdcc.c:165: error: for each function it appears in.) linux-2.6/drivers/mmc/host/msm_sdcc.c:167: error: 'MSM_SDC2_PHYS' undeclared (first use in this function) linux-2.6/drivers/mmc/host/msm_sdcc.c:169: error: 'MSM_SDC3_PHYS' undeclared (first use in this function) linux-2.6/drivers/mmc/host/msm_sdcc.c:171: error: 'MSM_SDC4_PHYS' undeclared (first use in this function) So we add a Kconfig check to prevent this.
