[PATCH v2 1/9] initrd: remove ASCII spinner

[Julian Stecklina via B4 Relay]

From: Julian Stecklina <julian.stecklina@xxxxxxxxxxxxxxxxxxxxx>

Writing the ASCII spinner probably costs more cycles than copying the
block of data on some output devices if you output to serial and in
all other cases it rotates at lightspeed in 2025.
