Most predefined TLB tables don't have memory coherence bit set for SDRAM. This wasn't an issue before invalidate_dcache_range() function was enabled. Without the coherence bit, dcache invalidation doesn't automatically flush the cache. The coherence bit is already set when dynamic TLB table is used. For some boards with different SPL boot method, or with legacy fixed setting, this bit needs to be set in TLB files. Signed-off-by: York Sun <york.sun@nxp.com> |

Overview -------- P1022ds is a Low End Dual core platform supporting the P1022 processor of QorIQ series. P1022 is an e500 based dual core SOC. Pin Multiplex(hwconfig setting) ------------------------------- Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex via hwconfig, i.e: 'setenv hwconfig usb2' to enable USB2 and disable eTsec2 'setenv hwconfig tdm' to enable TDM and disable Audio 'setenv hwconfig audclk:12' to enable Audio(codec clock sources is 12MHz) and disable TDM 'setenv hwconfig 'usb2;tdm' to enable USB2 and TDM, disable eTsec2 and Audio 'setenv hwconfig 'usb2;audclk:11' to enable USB2 and Audio(codec clock sources is 11MHz), disable eTsec2 and TDM Warning: TDM and AUDIO can not enable simultaneous ! and AUDIO codec clock sources only setting as 11MHz or 12MHz ! 'setenv hwconfig 'audclk:12;tdm' --- error ! 'setenv hwconfig 'audclk:11;tdm' --- error ! 'setenv hwconfig 'audclk:10' --- error !
