/*
There are 2 sets of general I/O -->
1. GPIO (shared between ARM & DSP, configured by ARM)
2. MPUIO which can be used only by the ARM.
Base address FFFB:5000 is where the ARM accesses the MPUIO control registers
(see 7.2.2 of the TRM for MPUIO reg definitions).
Base address E101:5000 is reserved for ARM access of the same MPUIO control
regs, but via the DSP I/O map. This address is unavailable on 1510.
Base address FFFC:E000 is where the ARM accesses the GPIO config registers
directly via its own peripheral bus.
Base address E101:E000 is where the ARM can access the same GPIO config
registers, but the access takes place through the ARM port interface (called
API or MPUI) via the DSP's peripheral bus (DSP I/O space).
Therefore, the ARM should setup the GPIO regs thru the FFFC:E000 addresses
instead of the E101:E000 addresses. The DSP has only read access of the pin
control register, so this may explain the inability to write to E101:E018.
Try accessing pin control reg at FFFC:E018.
