Hi,
it may also be a Cedarview chipset. According to my knowledge there is no support for Cedarview chipset in coreboot. However coreboot has slightly older (1 year older) chipset support - Pineview.
My experience is very little when it comes to older chipsets, but judging by how sanydbridge and ivybridge works, pineview and cedarview should have most thing in common. That said, i would try to go out from pineview northbridge in coreboot. The next question is which southbirdge to choose. There are two mainboards based on pineview. Most likely you would have to select:
select CPU_INTEL_SOCKET_FCBGA559 select NORTHBRIDGE_INTEL_PINEVIEW select SOUTHBRIDGE_INTEL_I82801GX
in your mainboard Kconfig. The CPU socket also matches according to Intel ARK about N2600

The initialization for that particular silicon is native so no FSP required. Since it may be hard to debug, I advise to get a USB debug dongle and enable it in coreboot menuconfig. But before that, find out which USB port on this netbook is connected to EHCI debug port. Typically it is the first port on the root hub. You can find it out using lspci and lsusb in Linux (by connecting a USB-UART dongle for example to the investigated port). The dongles supported by coreboot are: FTDI232H/FTDI2232H, or you can use BeagleBone board.
