Sandpoint8240 Linux porting

[윤동석]

Dear

I am working custom 8240Board. I started with Sandpoint8240 LSP at HHL2.0
I faced problem with OpenPIC interrupt setting. At Sandpoint8240 LSP use 8259
but I don't use 8259 interrupt controller so I want to remove the codes.
Could you let me know  how to map Interrupt controller ?
I would like to use external Intterrupt like followings

INT#0 : not useed
INT#1 : Ethernet Dec21... chip
INT#2 : Not Used
INT#3 : Not Used
INT#4 : Serial Console

I am attatching Serial Console Output

인생의 바다, 우린 작은 돗단배를 타고 여행을 한다
아직 항구에  정박 중인 배, 서로 경쟁하며 거센 파도
헤치고 나아가는 배. 갈길 몰라 방황하는 배..........
당신은 어느 배를 타고 있나요  ?
