Firmware update management

A computing device for firmware update management, comprising:

• a processing resource;
• and
• a memory resource storing non-transitory machine-readable instructions to cause the processing resource to:
• receive an update package including a cryptographic filter and a firmware update;
• retrieve, by a bootloader of the computing device, a unique identifier of the computing device from read-only memory of the computing device;
• compute a hash of the unique identifier;
• determine whether the computing device is included in a target device list processed by the cryptographic filter by comparing the hash to a number of hashed device identifiers in the target device list;
• and
• cause firmware of the computing device to be updated via the firmware update in response to the hash matching a hashed device identifier of the number of hashed device identifiers in the target device list.

A non-transitory computer readable medium storing instructions executable by a processing resource to cause the processing resource to:

• receive, from a remote computing device, an update package including a cryptographic filter and a firmware update;
• retrieve, by a bootloader, a unique identifier of a computing device from read-only memory of the computing device, wherein the bootloader resides in the read-only memory;
• compute a hash of the unique identifier;
• determine, by the bootloader, whether the computing device is included in a target device list processed by the cryptographic filter by comparing the hash to a number of hashed device identifiers in the target device list;
• and
• cause firmware of the computing device to be updated via the firmware update in response to the hash matching a hashed device identifier of the number of hashed device identifiers in the target device list.
