Virgil Dupras cdd0b64570 Modify userspace .org and RAMSTART expectations
Instead of expecting a `USER_CODE` symbol to be set, we expect `.org` to be
set in all userspace glue code. This gives us more flexibility with regards to
how we manage that.

Moreover, instead of making `USER_RAMSTART` mandatory, we make it default to
the end of the binary, which is adequate in a majority of cases.

Will be useful for my upcoming mega-commit... :)

; at28w - Write to AT28 EEPROM
;
; Write data from the active block device into an eeprom device geared as
; regular memory. Implements write polling to know when the next byte can be
; written and verifies that data is written properly.
;
; Optionally receives a word argument that specifies the number or bytes to
; write. If unspecified, will write until max bytes (0x2000) is reached or EOF
; is reached on the block device.
