charset="utf-8" According to the datasheet the previous ESP command remains in the ESP_CMD register, which caused a problem when consecutive TI commands were issued as it becomes impossible for the state machine to know when the first TI command finishes. This was the original reason for introducing the ti_cmd field which kept track of the last written command for this purpose. However closer reading of the datasheet shows that a TI command that terminates due to a change of SCSI target phase resets the ESP_CMD register to zero which solves this problem. Now that this has been fixed in the previous commit, remove the unneeded ti_cmd field and access the ESP_CMD register directly instead. Bump the vmstate_esp version to indicate that the ti_cmd field is no longer included.

When accumulating data in the FIFO don't raise the INTR_BS interrupt until = the TI command is issued, otherwise the unexpected interrupt can confuse the ho= st. In particular this is needed to prevent the MacOS Disk Utility from failing when switching non-DMA transfers to use esp_do_nodma().

charset="utf-8" Currently any write to the ESP FIFO in the MESSAGE OUT or COMMAND phases wi= ll manually raise the bus service interrupt. Instead of duplicating the interr= upt logic in esp_reg_write(), update esp_do_nodma() to correctly process incomi= ng FIFO data during the MESSAGE OUT and COMMAND phases. Part of this change is= to call esp_nodma_ti_dataout() from handle_ti() to ensure that the DATA OUT ph= ase FIFO transfer only occurs when executing a non-DMA TI command instead of for each byte entering the FIFO. One slight complication is that NextSTEP uses multiple TI commands to trans= fer the CDB one byte at a time (as opposed to loading the FIFO and using a sing= le TI command), so it is necessary to determine the expected length of the SCSI CDB being received. This is handled by the introduction of a new esp_cdb_length() function which returns the expected SCSI CDB length based upon the first command byte.

For DATA IN and DATA OUT phases, t= he transfer is complete when TC =3D=3D 0 and the updated logic will now handle= TC underflow correctly, which makes it just about impossible to manually manip= ulate the FIFO during a DMA transfer.

Implement the DMA Transfer Pad command for the DATA phases which is used by the NeXTCube firmware in the DATA IN phase to ignore part of the incoming S= CSI data as it is copied into memory.

charset="utf-8" Currently the DRQ IRQ is updated every time DMA data is sent/received which is both inefficient and causes excessive logging of the DRQ state. Add a new drq_state bool that only updates the DRQ IRQ if its state changes. This commit adds the new drq_state bool to the migration state: since the version number has already been increased earlier in the series, there is no need to repeat it again here. The DRQ IRQ is (currently) only used for PDMA transfers which already have a migration break in this series so there are no problems setting its value post-load.
