new-flash-memory

Description

Limitations

• Many vendor-specific commands are not implemented.
• Erase suspend will complete the erase, and resume will then simply be ignored.

Interfaces Implemented

Notifiers

cell-change

Notifier that is triggered after the object's cell was changed.

object-delete

Notifier that is triggered just before Simics object is deleted.

queue-change

Notifier that is triggered after the object's clock was changed. New clock can be obtained with the SIM_object_clock function.

Attributes

command_set

Optional attribute; read/write access; type: i
If no CFI structure is provided, this attribute should be set to indicate the command-set to use. Default is 0 (invalid command-set).

cfi_query

Optional attribute; read/write access; type: n|d|[i+]

device_id

Optional attribute; read/write access; type: i|[i+]
Device ID/code as used in Intel identifier codes and AMD autoselect mode. Default is 0.

manufacturer_id

Optional attribute; read/write access; type: i
Manufacturer ID/code as used in Intel identifier codes and AMD autoselect mode. Default is 0.

write_buffer_size

Optional attribute; read/write access; type: i
Write buffer size *in bytes* for write buffer commands. Default is 32 (standard value for Intel Strataflash®).

interleave

Required attribute; read/write access; type: i
Interleave (number of parallel flash memory chips).

bus_width

Required attribute; read/write access; type: i
Total width (in bits) of the data path connected to the flash device.

max_chip_width

Optional attribute; read/write access; type: i
Maximum data width (for example, specified as 16 for a x8/x16 capable device).

unit_size

Required attribute; read/write access; type: [i+]
A list of block/sector sizes.

ignore_timing

Optional attribute; read/write access; type: i
Obsolete attribute since timing is not modeled. Kept for backward compatibility only.

unit_erase_time

Optional attribute; read/write access; type: f
Obsolete attribute since timing is not modeled. Kept for backward compatibility only.

strict_cmd_set

Optional attribute; read/write access; type: i
If set to 1, warnings that the command-set is misused become errors. Default is 0.

storage_ram

Required attribute; read/write access; type: o
RAM object providing the backing store area.

accept_smaller_reads

Pseudo attribute; read/write access; type: i
Obsolete, do not use.

accept_smaller_writes

Pseudo attribute; read/write access; type: i
Obsolete, do not use.

big_endian

Optional attribute; read/write access; type: i
If 1, the flash device will behave as a big endian device. If 0, it will behave as a little endian device. Default is 0.

intel_chip_erase

Optional attribute; read/write access; type: b
If TRUE, the flash device supports Intel chip erase command operations. If FALSE, Intel chip erase command is flagged as error. Default is FALSE.

intel_program_verify

Optional attribute; read/write access; type: b
If TRUE, the flash device supports Intel program verify command operations. If FALSE, Intel program verify command is flagged as error. Default is FALSE.

intel_write_buffer

Optional attribute; read/write access; type: i
If 1, the flash device supports Intel write buffer operations. If 0, Intel write buffer operations are ignored. Default is 0.

intel_protection_program

Optional attribute; read/write access; type: i
If 1, the flash device supports Intel protection program operations. If 0, Intel protection program operations are ignored. Default is 0.

intel_configuration

Optional attribute; read/write access; type: i
If 1, the flash device supports Intel configuration operations. If 0, Intel configuration operations are ignored. Default is 0.

intel_lock

Optional attribute; read/write access; type: i
If 2, the flash device supports advanced lock/unlock/lock down operations. If 1, the flash device supports simple lock/unlock all operations. If 0, lock operations are ignored. Default is 0.

amd_ignore_cmd_address

Optional attribute; read/write access; type: i
If 1, the address will be ignored when parsing AMD commands. Default is 0.

lock_status

Optional attribute; read/write access; type: [[i*]*]
Lock status for all units.

hardware_lock_status

Optional attribute; read/write access; type: [[i*]*]
Hardware lock status for all units (for Intel advanced lock system).

unit_status

Optional attribute; read/write access; type: [[i*]*]
Status for all units.

ppb_bits

Optional attribute; read/write access; type: [[i*]*]

busy_signal_targets

Optional attribute; read/write access; type: [n|o|[os]*]
(dst_object, dst_signal)* The destination device and signal name to connect the busy signal of the chips to. The destinations should implement the signal interface. Without a timing model, the device will never raise the busy signal.
