Linux/DRA745: Please help to explain of uEnv.txt parameter's meaning

Hi Widic,

> elevator=noop
this sets the kernel to use "Noop" I/O scheduler:
en.wikipedia.org/.../Noop_scheduler

> rootwait
the kernel will wait (indefinitely) for root device to show up. Useful for devices that are detected asynchronously (e.g. USB and MMC devices).

> earlyprintk
Enables early boot messages

> fixrtc
fixrtc is related to RTC SS. The kernel option 'fixrtc' exists to set the system time from the last mount time from the rootfs, check here for more details:
e2e.ti.com/.../2233487

> omapdrm.num_crtc=2
Number of CRTCs:
e2e.ti.com/.../2233603

> consoleblank=0
Disables console blanking

> cma=128M@0xB0000000
Sets the size of kernel global memory area for contiguous memory allocations and optionally the
placement constraint by the physical address range of memory allocations. A value of 0 disables CMA
altogether. For more information, see include/linux/dma-contiguous.h

> rootfstype=ext4
Set root filesystem type
