Recent changes caused that the HMI10 board now is included in the boards built by MAKEALL, which revealed that compilation for this board has been broken for a long time: ps2ser.c: In function 'ps2ser_init': ps2ser.c:155: error: 'UART_LCR' undeclared (first use in this function) ps2ser.c:155: error: (Each undeclared identifier is reported only once ps2ser.c:155: error: for each function it appears in.) ps2ser.c:156: error: 'UART_DLL' undeclared (first use in this function) ps2ser.c:157: error: 'UART_DLM' undeclared (first use in this function) ps2ser.c:159: error: 'UART_IER' undeclared (first use in this function) ps2ser.c:160: error: 'UART_MCR' undeclared (first use in this function) ps2ser.c:161: error: 'UART_FCR' undeclared (first use in this function) ps2ser.c:162: error: 'UART_FCR_ENABLE_FIFO' undeclared (first use in this function) ps2ser.c:166: error: 'UART_LSR' undeclared (first use in this function) ps2ser.c: In function 'ps2ser_putc': ps2ser.c:198: error: 'UART_LSR' undeclared (first use in this function) ps2ser.c:200: error: 'UART_TX' undeclared (first use in this function) ps2ser.c: In function 'ps2ser_getc_hw': ps2ser.c:224: error: 'UART_LSR' undeclared (first use in this function) ps2ser.c:225: error: 'UART_RX' undeclared (first use in this function) ps2ser.c: In function 'ps2ser_interrupt': ps2ser.c:293: error: 'UART_IIR' undeclared (first use in this function) The board is orphaned, and AFAICT has reached EOL. Drop support for it. Signed-off-by: Wolfgang Denk <wd@denx.de>
