For A13-OLinuXinoM_FEL_config and gcc version 4.8.2 (Gentoo 4.8.2-r1 p1.4-ssptest, pie-0.5.9-ssptest) == before == $ armv7a-hardfloat-linux-gnueabi-size u-boot-spl text data bss dec hex filename 11010 372 16 11398 2c86 u-boot-spl == after == $ armv7a-hardfloat-linux-gnueabi-size u-boot-spl text data bss dec hex filename 8762 372 16 9150 23be u-boot-spl Having extra SRAM space headroom is nice. Also the unification and the use of Thumb2 code everywhere means that any possible compiler bugs are likely to affect both regular and FEL builds in the same way. Should I send a v2 patch with an updated commit message? -- Best regards, Siarhei Siamashka -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
