phosphor-isolation

[James Feist]

I enabled phosphor-isolation on my system and noticed that kcs no longer 
worked afterwards. Commenting out this section:

https://github.com/openbmc/meta-phosphor/blob/a1cee09419cb1467c3d2b7bf996b40089f0d06f4/aspeed-layer/recipes-bsp/u-boot/files/0001-aspeed-Disable-unnecessary-features.patch#L230

+	/* iLPC2AHB */
+	val = readl(AST_SCU_BASE + AST_SCU_HW_STRAP1);
+	val |= SCU_HW_STRAP_LPC_DEC_SUPER_IO;
+	writel(val, AST_SCU_BASE + AST_SCU_HW_STRAP1);


Seems to make KCS work again. Do we need this part set? If so, should we 
create a phosphor-isolation-kcs and phosphor-isolation-bt?


Thanks
