5897 * a translation error which is unrecoverable.
5898 * The Workaround is intended to make sure that when this happens nothing fatal
5899 * will occur. The workaround:
5900 * 1. First PF driver which loads on a path will:
5901 * a. After taking the chip out of reset, by using pretend,
5902 * it will write "0" to the following registers of

5907 * And for itself it will write '1' to
5908 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
5909 * dmae-operations (writing to pram for example.)
5910 * note: can be done for only function 6,7 but cleaner this
5911 * way.
5912 * b. Write zero+valid to the entire ILT.
5913 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
5914 * VNIC3 (of that port). The range allocated will be the
5915 * entire ILT. This is needed to prevent ILT range error.
5916 * 2. Any PF driver load flow:
5917 * a. ILT update with the physical addresses of the allocated
5918 * logical pages.
5919 * b. Wait 20msec. - note that this timeout is needed to make
5920 * sure there are no requests in one of the PXP internal
5921 * queues with "old" ILT addresses.
5922 * c. PF enable in the PGLC.
5923 * d. Clear the was_error of the PF in the PGLC. (could have
5924 * occured while driver was down)
5925 * e. PF enable in the CFC (WEAK + STRONG)
5926 * f. Timers scan enable
5927 * 3. PF driver unload flow:
5928 * a. Clear the Timers scan_en.
5929 * b. Polling for scan_on=0 for that PF.
5930 * c. Clear the PF enable bit in the PXP.
5931 * d. Clear the PF enable in the CFC (WEAK + STRONG)
5932 * e. Write zero+valid to all ILT entries (The valid bit must
5933 * stay set)
5934 * f. If this is VNIC 3 of a port then also init
5935 * first_timers_ilt_entry to zero and last_timers_ilt_entry
5936 * to the last enrty in the ILT.
5937 *
5938 * Notes:
5939 * Currently the PF error in the PGLC is non recoverable.
5940 * In the future the there will be a recovery routine for this error.
5941 * Currently attention is masked.
5942 * Having an MCP lock on the load/unload process does not guarantee that
5943 * there is no Timer disable during Func6/7 enable. This is because the
5944 * Timers scan is currently being cleared by the MCP on FLR.
5945 * Step 2.d can be done only for PF6/7 and the driver can also check if
5946 * there is error before clearing it. But the flow above is simpler and
5947 * more general.
5948 * All ILT entries are written by zero+valid and not just PF6/7
5949 * ILT entries since in the future the ILT entries allocation for
5950 * PF-s might be dynamic.
