Atish Patra	2e5cc9051b	lib: Fix timer for 32 bit ... To read 64bit time in 32 bit we have to read lower & upper half separately and 'or' them together. However, upper half time may have changed by the time we read lower half. Thus, the resultant 64 bit time may not be accurate. Consider lower half time value only if upper half time value has not changed. Signed-off-by: Atish Patra <atish.patra@wdc.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>	2019-08-31 13:13:12 +05:30
Atish Patra	75229705a0	platform: Remove the ipi_sync method from all platforms. ... OpenSBI manages outstanding TLB flush requests by queueing them in a fifo synchronously. An ipi sync which uses an atomic operation on MMIO address is no longer required. Remove the ipi sync method from platform header and all usage.

Atish Patra	793e5e1184	platform: Move platform common to lib/utils. ... Currently, platform/common contains platform/non-platform specific common minimal drivers and libraries. This is helpful is all platforms are built within opensbi framework. Move them to lib/utils so that any external platform code also can reuse the minimalistic drivers or other common libraries. This patch doesn't introduce any functional changes. Signed-off-by: Atish Patra <atish.patra@wdc.com> Acked-by: Anup Patel <anup.patel@wdc.com>	2019-06-19 09:48:56 +05:30
