Hi all, I run across an issue when startup the MPC8536DS board by using the latest git tree. The system hanged when initialized the DDR. U-Boot 2009.08-00197-g15fba32 (Sep 17 2009 - 18:15:50) CPU: 8536E, Version: 1.1, (0x803f0091) Core: E500, Version: 3.0, (0x80210030) Clock Configuration: CPU0:1499.985 MHz, CCB:499.995 MHz, DDR:333.330 MHz (666.660 MT/s data rate) (Asynchronous), LBC:31.250 MHz L1: D-cache 32 kB enabled I-cache 32 kB enabled Board: MPC8536DS Sys ID: 0x15, Sys Ver: 0x10, FPGA Ver: 0x13, vBank: 0 I2C: ready DRAM: Initializing....ERROR 2 GB left unmapped DDR: I traced the code and found the variable law_sz_enc got an error value when call __ilog2_u64 in the function set_ddr_laws. The inline function __ilog2_u64 will call fls inline function finally, but the fls is defined as a variable by the commit 52d61227b66d4099b39c8309ab37cb67ee09a405 in the platform specific bitops.h file. include/asm-ppc/bitops.h: static __inline__ int fls(unsigned int x) { return __ilog2(x) + 1; } #define fls
So when called fls, which one will be used? >From the experiments, I got the latter called, but I don't find the root reason, any clues? Thanks, Mingkai
