Re: [U-Boot] [u-boot-release] [PATCH 06/10][v3] armv8: fsl-layerscape: Add support of QorIQ LS1012A SoC

From: Prabhakar Kushwaha:

--- a/arch/arm/cpu/armv8/fsl-layerscape/fsl_lsch2_speed.c +++ b/arch/arm/cpu/armv8/fsl-layerscape/fsl_lsch2_speed.c unsigned int cpu;

• unsigned int svr, ver; const u8 core_cplx_pll[8] = {

...

• 	FSL_CHASSIS2_RCWSR0_MEM_PLL_RAT_MASK;
  

• svr = gur_in32(&gur->svr);
• ver = SVR_SOC_VER(svr);
• if (ver == SVR_LS1012) {

• sys_info->freq_ddrbus *= (gur_in32(&gur->rcwsr[0]) >>
  

• 		FSL_CHASSIS2_RCWSR0_SYS_PLL_RAT_SHIFT) &
  

• 		FSL_CHASSIS2_RCWSR0_SYS_PLL_RAT_MASK;
  

• } else {

• sys_info->freq_systembus *= (gur_in32(&gur->rcwsr[0]) >>
  

• 		FSL_CHASSIS2_RCWSR0_SYS_PLL_RAT_SHIFT) &
  

• 		FSL_CHASSIS2_RCWSR0_SYS_PLL_RAT_MASK;
  

Why introduce a run-time check for every board when this could be handled at compile time?
