During spi transfer, for example:
sspi 1:1.0 8 ff
the rx_len values will be:
rx_len = 0
rx_len = 4294967295
This caused a busy looping during xfer, this patch fixes it
by adding a check while reading the rx fifo

Hi Jagannadha,
I am working on the zynq board, we have spi0 connected to flash chip,
which works fine. The spi1 is connected to display we want to use sspi
command to power up the display.
I have enabled, the CONFIG_SPI command, but when I use the sspi
command I get tx timeouts.
Cheers,
--Prabha
Hello,
I have a display connected to spi-1, there is no driver for display,
we want to use sspi commands to program the display. since there isnt
any device node to spi-1 connected and when issued with sspi commands
it returns with invalid device 1:0
Cheers,

Hello All,
It's quite a long time, since I touched u-boot code, I was working on
adding a slave SPI device to DM, can anyone point me to a sample
driver.
Cheers,
