First of all. v1.1.6 is really old. I suggest that you use the current (latest) version instead.
I am using the hello world application from the examples folder. I had no issues in loading and executing it. Now I have enabled SPI interrupt in the application. I have written for SPI loopback. My issue is, as there is no interrupt handler defined for the SPI in uboot, whenever i execute my application, it says "Masking bogus interrupt for Vector 0x08". I am calling "install_irq_handler" function for assigning my own interrupt handler for SPI as part of my application itself. I can understand that, there is no exclusive handler for SPI in uboot, so it is disabling the SPI interrupt and printing the BOGUS INTERRUPT message. Now how do I get rid of this and have my own interrupt handler??
You just need to install you "own" interrupt handler. This is done via install_hdlr(). See examples/interrupt.c.
