A lot of patches are outdated versions of upstreamed patches and drivers. So lets pull in the upstreamed patches and reorder remaining ones. This drops the unnecessary 721-dts-ipq4019-add-ethernet-essedma-node.patch which adds nodes for not yet in OpenWrt IPQESS driver.

Subject: [PATCH] ARM: dts: qcom: Add nodes for SMP boot in IPQ40xx
|
|
|
|
Add missing nodes and properties to enable SMP
|
|
support on IPQ40xx devices.
|
|
|
|
Booting without "saw_l2" node:
|
|
|
|
[ 0.001400] CPU: Testing write buffer coherency: ok
|
|
[ 0.001856] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
|
|
[ 0.060163] Setting up static identity map for 0x80300000 - 0x80300060
|
|
[ 0.080140] rcu: Hierarchical SRCU implementation.
|
|
[ 0.120258] smp: Bringing up secondary CPUs ...
|
|
[ 0.200540] CPU1: failed to boot: -19
|
|
[ 0.280689] CPU2: failed to boot: -19
|
|
[ 0.360874] CPU3: failed to boot: -19
|
|
[ 0.360966] smp: Brought up 1 node, 1 CPU
|
|
[ 0.360979] SMP: Total of 1 processors activated (96.00 BogoMIPS).
|
|
[ 0.360988] CPU: All CPU(s) started in SVC mode.
|
|
|
|
Then, booting with "saw_l2" node present (this patch applied):
|
|
|
|
[ 0.001450] CPU: Testing write buffer coherency: ok
|
|
[ 0.001904] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
|
|
[ 0.060161] Setting up static identity map for 0x80300000 - 0x80300060
|
|
[ 0.080137] rcu: Hierarchical SRCU implementation.
|
|
[ 0.120252] smp: Bringing up secondary CPUs ...
|
|
[ 0.200958] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001
|
|
[ 0.281091] CPU2: thread -1, cpu 2, socket 0, mpidr 80000002
|
|
[ 0.361264] CPU3: thread -1, cpu 3, socket 0, mpidr 80000003
|
|
[ 0.361430] smp: Brought up 1 node, 4 CPUs
|
|
[ 0.361460] SMP: Total of 4 processors activated (384.00 BogoMIPS).
|
|
[ 0.361469] CPU: All CPU(s) started in SVC mode.
