This group will contain: b, bl, bc.
The first 2 instructions (b, bl) will be verified by jumping to
- a fixed address and checking whether control was transfered to
+ a fixed address and checking whether control was transferred to
that very point. For the bl instruction the value of the link
register will be checked as well (using mfspr). To verify the bc
instruction various combinations of the BI/BO fields, the CTR
devices are detected. If CONFIG_SYS_POST_I2C_ADDRS is not defined
the test will pass if any I2C device is found.
+The CONFIG_SYS_POST_I2C_IGNORES define can be used to list I2C
+devices which may or may not be present when using
+CONFIG_SYS_POST_I2C_ADDRS. The I2C POST test will pass regardless
+if the devices in CONFIG_SYS_POST_I2C_IGNORES are found or not.
+This is useful in cases when I2C devices are optional (eg on a
+daughtercard that may or may not be present) or not critical
+to board operation.
