Add exp_i2c_scom driver that will be consumed by HB/SBE platforms
Browse files Browse the repository at this point in the history 
This commit adds a new exp_i2c_scom.H file which contains two
functions, i2c_get_scom and i2c_put_scom. These functions will
take in a fapi2 OCMB target, an address and a buffer that either
contains scom data to write or space for scom data to be written
to. The functions use the fapi2::puti2c / fapi2::geti2c interfaces
to perform the scoms.

<description>
First Byte data returned from the i2c register read contains
the size of the remaining bytes returned. This should match
the number of bytes we requested.

<description>
First Byte of the address passed to i2c_scom operation did not match
what was required for IBM scom. I2c scoms associated with 64 bits of
are assumed to be IBM scoms and must have 0x08 set in the first byte
of the address.

<description>
First Byte of the address passed to i2c_scom operation had 0x08 set which
indicates IBM scom. But the data associated with the address does not
match IBM scom data size.
